ABAP 100 道面试题

ABAP 100 道面试题text:1. What is the typical structure of an ABAP/4 program?HEADER,BODY,FOOTER.2. What are field symbols and field groups.?Have you used "component idx of structure"clause with field groups?Field symbols:-Field groups :-3. What should be theapproach for writing a BDC program?STEP 1: CONVERTING THE LEGACY SYSTEM DATA TO A FLAT FILE to internal tableCALLED "CONVERSION".STEP 2: TRANSFERING THE FLAT FILE INTO SAP SYSTEM CALLED "SAP DATA TRANSFER".STEP 3:DEPENDING UPON THE BDC TYPE i)call transaction(Write the program explicity)ii) create sessions (sessions arecreated and processed.if success data will transfer).4. What is a batch input session?BATCH INPUTSESSION is an intermediate step between internal table and database table.Data along with the action is stored insession ie data for screen fields, to which screen it is passed,program name behind it, and how next screen is processed.5. What is the alternative to batch input session?Call transaction.6. A situation: AnABAP program creates a batch input session.We need to submit the program and the batch session in back ground.How to do it?Please go to SM36 and create background job by giving job name,job class and job steps(JOB SCHEDULING)8. What are the problems in processing batch input sessions?How is batch inputprocess different from processing online?PROBLEMS:-i) If the user forgets to opt for keep sessionthen the session will be automatically removed from the session queue(log remains). However if session is processed we maydelete it manually.ii)if session processing fails data will not be transferred to SAP database table.10.What are the different types of data dictionary objects?tables, structures, views, domains, data elements,lock objects, Matchcode objects.11. How many types of tables exists and what are they in data dictionary?4 types of tablesi)Transparent tables - Exists with the same structure both in dictionary as well as indatabase exactly with the same data and fields. Both Opensql and Nativesql can be used.ii)Pool tables & iii)Cluster tables -These are logical tables that are arranged as records of transparent tables.one cannot use native sqlon these tables(only opensql).They are not managable directly using database system tools.iv)Internal tables- .12. What is the step by step process to create a table in data dictionary?step 1: creatingdomains(data type,field length,range).step 2: creating data elements(properties and type for a tablefield).step 3: creating tables(SE11).13. Can a transparent table exist in data dictionary but notin the data base physically?No. Transporent tables do exist with the same structure, both in the dictionary aswell as in database, exactly with the same data and the fields.14. What are the domains and data elements?DOMAINS : FORMAL DEFINITION OF THE DATA TYPES.THEY SET ATTRIBUTES SUCH AS DATA TYPE,LENGTH,RANGE.DATA ELEMENT : A FIELD IN R/3 SYSTEM IS A DATA ELEMENT.15. Can you create a table with fields notreferring to data elements?YES. eg:- ITAB LIKE SPFLI.here we are referening to a data object(SPFLI) not dataelement.16. What is the advantage of structures? How do you use them in the ABAP programs?The mostimportant advantage of the structures is that they have global existence (i.e.; these could be used by any other programwithout creating it again).17. What does an extract statement do in the ABAP program?Onceyou have declared the possible record types as field groups and defined their structure, you can fill the extract dataset using the following statements:EXTRACT .When the first EXTRACT statement occurs in a program, thesystem creates the extract dataset and adds the first extract record to it. In each subsequent EXTRACT statement, the newextract record is added to the datasetEXTRACT HEADER.When you extract the data, the record is filled withthe current values of the corresponding fields.As soon as the system has processed the first EXTRACT statement for afield group , the structure of the corresponding extract record in the extract dataset is fixed. You can no longer insert new fields into the field groups and HEADER. If you try to modify one of the field groups afterwards and use it in another EXTRACT statement, a runtime error occurs.By processing EXTRACT statements several times using differentfield groups, you fill the extract dataset with records of different length and structure. Since you can modify field groupsdynamically up to their first usage in an EXTRACT statement, extract datasets provide the advantage that you need notdetermine the structure at the beginning of the program.18. What is a collect statement? How is it differentfrom append?If an entry with the same key already exists, the COLLECT statement does not append a new line,but adds the contents of the numeric fields in the work area to the contents of the numeric fields in the existing entry.19. What is open sql vs native sql?ANS:-20. What does an EXEC SQL stmt do in ABAP?What is the disadvantage of using it?21. What is the meaning of ABAP/4 editor integrated with ABAP/4 datadictionary?22. What are the events in ABAP/4 language?Initialization, At selection-screen,Start-of-selection,end-of-selection,top-of-page,end-of-page, At line-selection,At user-command,At PF,Get,At New,AtLAST,AT END, AT FIRST.23. What is an interactive report?What is the obvious diff of such reportcompared with classical type reports?An Interactive report is a dynamic drill down report that produces thelist on users choice.diff:-a) THE LIST PRODUCED BY CLASSICAL REPORT DOESN'T allow user to interact with thesystemthe list produced by interactive report allows the user to interact with the system.b) ONCE ACLASSICAL REPORT EXECUTED USER LOOSES CONTROL.IR USER HAS CONTROL.c) IN CLASSICAL REPORT DRILLING IS NOT POSSIBLE.ININTERACTIVE DRILLING IS POSSIBLE.24.

What are the exceptions in functionmodule?COMMUNICATION_FAILURESYSTEM_FAILURE27. What is a function group?GROUP OF ALL RELATED FUNCTIONS.28. How are the date and time field values stored in SAP?DD.MM.YYYY. HH:MM:SS30. Name a few data dictionary objects?TABLES,VIEWS,STRUCTURES,LOCK OBJECTS,MATCHCODE OBJECTS.31. What happens when a table is activatedin DD?It is available for any insertion,modification and updation of records by any user.32. Whatis a check table and what is a value table?Check table will be at field level checking.Value tablewill be at domain level checking ex: scarr table is check table for carrid.33. What are match codes? describe?It is a similar to table index that gives list of possible values for either primary keys or non-primary keys.34. What transactions do you use for data analysis?35. What is table maintenance generator?36. What are ranges? What are number ranges?max,min values provided in selection screens.37. What are select options and how are they different from parameters?select options provideranges where as parameters do not.SELECT-OPTIONS declares an internal table which is automatically filled with valuesor rangesof values entered by the end user. For each SELECT-OPTIONS , the system creates a selection table. SELECT-OPTIONS FOR .A selection table is an internal table with fields SIGN, OPTION, LOW andHIGH.The type of LOW and HIGH is the same as that of .The SIGN field can take the following values: IInclusive (should apply) E Exclusive (should not apply)The OPTION field can take the following values: EQ Equal GTGreater than NE Not equal BT Between LE Lessthan or equal NB Not between LT Less than CP Contains pattern GE Greaterthan or equal NP No pattern.Select Options vs ParametersPARAMETERS allow users to enter a singlevalue into an internal field within a report.SELECT-OPTIONS allow users to fill an internal table with a range ofvalues.For each PARAMETERS or SELECT-OPTIONS statement you should define text elements by choosingGoto - Textelements - Selection texts - Change.Eg:- Parameters name(30).when the user executes the ABAP/4 program,aninput field for 'name' will appear on the selection screen.You can change the comments on the left side of the input fieldsby using text elements as described in Selection Texts.38. How do you validate the selection criteria of areport?And how do you display initial values in a selection screen?validate :- by using match codeobjects.display :- Parameters default 'xxx'.select-options for spfli-carrid.39. What are selection texts?40. What is CTS and what do you know about it?The Change and Transport System (CTS) is a tool that helps you to organize development projects in the ABAPWorkbench and in Customizing, and then transport the changes between the SAP Systems and clients in your system landscape.This documentation provides you with an overview of how to manage changes with the CTS and essential information onsetting up your system and client landscape and deciding on a transport strategy. Read and follow this documentation whenplanning your development project.For practical information on working with the Change and Transport System, seeChange and Transport Organizer and Transport Management System.41. When a program is created and need to betransported to prodn does selection texts always go with it? if not how do you make sure? Can you change the CTS entries? Howdo you do it?42. What is the client concept in SAP? What is the meaning of client independent?43. Are programs client dependent?Yes.Group of users can access these programs with aclient no.44. Name a few system global variables you can use in ABAP programs?SY-SUBRC,SY-DBCNT,SY-LILLI,SY-DATUM,SY-UZEIT,SY-UCOMM,SY-TABIX.....SY-LILLI IS ABSOLUTE NO OF LINES FROM WHICH THE EVENT WASTRIGGERED.45. What are internal tables? How do you get the number of lines in an internal table?How touse a specific number occurs statement?i)It is a standard data type object which exists only during theruntime of the program.They are used to perform table calculations on subsets of database tables and for re-organising the contents of database tables according to users need.ii)using SY-DBCNT.iii)The number of memoryallocations the system need to allocate for the next record population.46. How do you take care of performanceissues in your ABAP programs?Performance of ABAPs can be improved by minimizing the amount of data to betransferred.The data set must be transferred through the network to the applications, so reducing the amount OF time and also reduces the network traffic.Some measures that can be taken are:- Use views defined in the ABAP/4DDIC (also has the advantage of better reusability).- Use field list (SELECT clause) rather than SELECT *.-Range tables should be avoided (IN operator)- Avoid nested SELECTS.i)system toolsii)field symbols andfield groups.ans:-Field Symbols : Field symbols are placeholders for existing fields. A Field Symbol does notphysically reserve space for a field,but points to a field which is not known until runtime of the program. eg:-FIELD-SYMBOL [].Field groups : A field group combines several fields under one name.At runtime,the INSERTcommand is used to define which data fields are assigned to which field group.There should always be a HEADER fieldgroup that defines how the extracted data will be sorted,the data is sorted by the fields grouped under the HEADER fieldgroup.47. What are datasets?The sequential files(ON APPLICATION SERVER) are called datasets. Theyare used for file handling in SAP.48.

What are the techniques involved in using SAP supplied programs? Do youprefer to write your own programs to load master data? Why?52. What are logical databases? What are theadvantages/disadvantages of logical databases?To read data from a database tables we use logical database. Alogical database provides read-only access to a group of related tables to an ABAP/4 program.advantagesThe programmer need not worry about the primary key for each table.Because Logical database knows how the differenttables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.i)An easy-to-use standard user interface.ii)check functions which check that user input is complete,correct,and plausible.iii)meaningful data selection.iv)central authorization checks for database accesses.v)good read accessperformance while retaining the hierarchical data view determined by the application logic. disadvantagesi)If you donot specify a logical database in the program attributes,the GET events never occur.ii)There is noENDGET command,so the code block associated with an event ends with the next eventstatement (such as another GET oran END-OF-SELECTION).53. What specific statements do you using when writing a drill down report?AT LINE-SELECTION,AT USER-COMMAND,AT PF.54. What are different tools to report data in SAP? Whatall have you used?55. What are the advantages and disadvantages of ABAP/4 query tool?56. What are the functional areas? User groups? and how does ABAP/4 query work in relation tothese?57. Is a logical database a requirement/must to write an ABAP/4 query?59. What are Changeheader/detail tables? Have you used them?60. What do you do when the system crashes in the middle of a BDCbatch session?we will look into the error log file (SM35).61. What do you do with errors in BDCbatch sessions?We look into the list of incorrect session and process it again. To correct incorrect sessionwe analyize the session to determine which screen and value produced the error.For small errors in data we correct theminteractively otherwisemodify batch input program that has generated the session or many times even thedatafile.62. How do you set up background jobs in SAP? What are the steps? What are the event driven batch jobs?go to SM36 and create background job by giving job name,job class and job steps(JOB SCHEDULING)63.Is it possible to run host command from SAP environment?

SAP ABAP面试题目

ABAP面试题目问题一：锁对象（Lock Object）和FM（Function Module）激活锁定对象时，产生的FM 的名字是什么？答案：首先要在ABAP 字典中创建锁对象，然后才能在ABAP 程序中设锁。

创建锁对象时，系统会自动生成两个FM 来进行锁管理。

用于设锁的FM 为：ENQUEUE_<锁对象名>。

它用于在锁表（Lock Table）中生成一个锁项（Lock Entry）。

若设锁不成功的话，就会在Return 中反映出来。

用于释放锁的FM 为：DEQUEUE_<锁对象名>。

它用于从锁表中删除一个锁项。

在ABAP 程序中，只需使用"CALL FUNCITION ..." 语句就可以调用它们。

这两个锁FM 是在SAP 系统的一个特殊工作进程中执行的，专门进行锁管理。

它运行在一个单独的服务器上，而该服务器专门用于维护整个SAP 系统的主锁表（Central Locak Table）。

有两种锁类型：共享锁——只读锁，一个用户正在读数据时，阻止其他用户更改该数据。

独占锁——可写锁，一个用户正在修改数据时，阻止其他用户更改该数据。

问题二：更新方面的FM更新FM 分为V1 和V2，那么首先会执行哪一种更新类型呢？每种类型又是以哪种模式（异步、同步或本地）执行的呢？答案：V1 更新类型比V2 更新类型的优先级高，因此，V1 比V2 行执行。

V1 的执行模式可以为异步、同步或本地；V2 只能为异步执行。

问题三：ABAP 内存（ABAP Memory）交换在使用ABAP 内存的程序间进行数据交换时用到的两个语句是什么？答案：EXPORT to MEMORY ID 用于将数据复制到ABAP 内存，IMPORT from MEMORY ID 用于将数据从ABAP 内存复制到程序中。

在ABAP 内存间进行交换的数据必须在两个程序中都进行声明，并包含同样的数据声明。

ABAP面试及答案Interview+Questions

ABAP⾯试及答案Interview+Questions⾯试问题集1.数据效率尽量使⽤Select（max,min,sum,avg）和select single，for all enteris，⼆分法，append和collect loop⾥不能套select；避免使⽤select distinct，代替先sort，再delete；①抽取数据时，避免使⽤SELECT *, 尽量使⽤SELECT A B INTO TABLE ITAB这样的语句。

②不要使⽤SELECT...ENDSELECT语句。

③尽量避免在LOOP中访问数据库。

可以在之前先把数据取到内表，在LOOP中⽤READ TABLE WITHKEY ... BINARY SEARCH.进⾏读取对应的数据。

④⽤SORT代替ORDER BY。

⑤使⽤⼆分查找法。

READ TABLE的之前使⽤SORT TABLE BY对内表进⾏排序, 然后使⽤READ TABLEWITH KEY ...BINARY SEARCH.⑥避免使⽤SELECT DISTINCT语句。

在抽取数据到内表后⽤DELETE ADJACENT DUPLICATES语句来消除重复⾏。

⑦尽量多指定WHERE语句条件。

⑧在WHERE语句指定查询条件时，在同等条件下把包含等号的查询条件放到前边。

2.什么时候使⽤For all entries命令及其使⽤时的注意事项当需要在LOOP中使⽤查询语句时，⼀般使⽤For all entries。

注意事项：①IN条件所在的内表不能为空（如为空将取出全部的数据）；②数据库字段与内表中的关联⽐较字段必须具有相同的类型和长度，且不能在⽐较中使⽤操作符LIKE、BETWEEN和IN，同时不能使⽤ORDER BY⼦句。

③为避免删除并不重复的纪录，在定义内表时应尽可能多的指定关键字。

3.如何设置ALV的⿏标双击事件。

如何设置ALV的页眉和页脚ALV的⿏标双击事件：构造LS_LAYOUT的F2CODE属性设置为”&ETA”即可。

ABAP面试问题及侧重点

ABAP⾯试问题及侧重点ABAP⾯试1.简单的Report包括哪些东西2.Dialog 逻辑流以及相应的处理内容3.⽤过的⼏种增强⽅式：怎么找增强4.接⼝和函数的使⽤，⼀般遇到⾃⼰不会的函数怎么处理5.关联查询：INNER JOIN 与 LEFT JOIN 与 FOR ALL ENTRIES IN各⽤在什么情况ABAP基础：报表，功能，增强，接⼝，数据处理及性能优化（不管内部还是外部，均需了解）REPORT:1)数据定义；定义内表，结构，选择屏幕2)数据处理；包括屏幕数据检查，数据查询，内表数据处理等3)数据显⽰；定义字段⽬录，布局，特殊设置，CALL FM(习惯⽤REUSE_ALV_GRID_DISPLAY_LVC，LVC后期兼容和修改⽅便，也可以替代OO alv ) DIALOG:这是SAP的精华之⼀，不懂DIALOG，不⼊SAP门。

1)PBO;数据显⽰前处理，循环数据显⽰处理；循环之后⽆效修改和处理2)PAI;表⾏，字段处理，更新表⾏；事件处理增强：出⼝，BADI，隐式（常⽤的三种）；前两种可以⽤程序找（下篇⽂章），也可以找到程序对应的包，然后包⾥搜；隐式增强就是触发事件，DEBUG找地⽅加代码。

接⼝：就是查询，处理。

都会的查询：INNER 和LEFT，right是且与或的关系，确定都有的INNER,不确定有的，LEFT,RIGHT。

⽂本表不建议关联，适合单独查。

FOR ALL ENTRIES IN使⽤前最好对关键字排重，⾮空检查；内表超过10万不建议使⽤。

常规的性能优化：先查，后处理，LOOP下⾯尽量不⽤SELECT和LOOP，READ TABLE 要⼆分法排序；内表查询确定字段以及顺序，CORRESPONDING FIELDS使⽤时字段不要多。

考的都是基本的东西，考学习⾯，学习深度，学习能⼒，以及对SAP的认识和⾃⼰的思维逻辑能⼒附简单查询代码：凭证明细报表*&---------------------------------------------------------------------**& Report ZFIR025*&*&---------------------------------------------------------------------**&*&DESC :凭证明细表**&AUTHOR: LY*&*&DATE:20160721*&*&*&CHANGE LIST*& C DEVK901712 2016.07.21 08:11:04 LIYUAN*& C DEVK901869 2016.08.22 15:37:14 LIYUAN 增加本币⾦额*&---------------------------------------------------------------------*REPORT ZFIR025.TABLES:BKPF,BSEG,SKAT.TYPES:BEGIN OF TY_SHOW,MONAT TYPE BKPF-MONAT,BUDAT TYPE BKPF-BUDAT,BELNR TYPE BKPF-BELNR,BUKRS TYPE BKPF-BUKRS,BKTXT TYPE BKPF-BKTXT,GJAHR TYPE BKPF-GJAHR,BLART TYPE BKPF-BLART,WAERS TYPE BKPF-WAERS,USNAM TYPE BKPF-USNAM,AWKEY TYPE BKPF-AWKEY,HKONT TYPE BSEG-HKONT,KUNNR TYPE BSEG-KUNNR,LIFNR TYPE BSEG-LIFNR,KOSTL TYPE BSEG-KOSTL,FKBER TYPE BSEG-FKBER,WRBTR TYPE BSEG-WRBTR,WRBTRS TYPE BSEG-WRBTR,WRBTRH TYPE BSEG-WRBTR,SHKZG TYPE BSEG-SHKZG,MATNR TYPE BSEG-MATNR,XNEGP TYPE BSEG-XNEGP,RSTGR TYPE BSEG-RSTGR, "原因代码TXT40 TYPE T053S-TXT40, "原因代码⽂本LTEXT TYPE CSKT-LTEXT, "成本中⼼⽂本DMBTR TYPE BSEG-DMBTR,DMBTRS TYPE BSEG-DMBTR,DMBTRH TYPE BSEG-DMBTR,TXT50 TYPE SKAT-TXT50,GSBER TYPE BSEG-GSBER,END OF TY_SHOW,BEGIN OF TY_T053S,RSTGR TYPE BSEG-RSTGR, "原因代码BUKRS TYPE BSEG-BUKRS, "原因代码TXT40 TYPE T053S-TXT40, "原因代码⽂本END OF TY_T053S,BEGIN OF TY_CSKT,KOSTL TYPE BSEG-KOSTL, "原因代码LTEXT TYPE CSKT-LTEXT, "原因代码⽂本END OF TY_CSKT.DATA:GT_SHOW TYPE TABLE OF TY_SHOW,GW_SHOW LIKE LINE OF GT_SHOW,GT_T053 TYPE TABLE OF TY_T053S,GW_T053 LIKE LINE OF GT_T053,GT_CSKT TYPE TABLE OF TY_CSKT,GW_CSKT LIKE LINE OF GT_CSKT.DATA:GT_FIELDCAT TYPE LVC_T_FCAT.DATA GS_FIELDCAT LIKE LINE OF GT_FIELDCAT.DATA LS_LAYOUT TYPE LVC_S_LAYO.DEFINE APPEND_FIELDCAT .CLEAR GS_FIELDCAT.GS_FIELDCAT-FIELDNAME = &1.GS_FIELDCAT-SCRTEXT_L = &2.GS_FIELDCAT-OUTPUTLEN = &3.GS_FIELDCAT-NO_ZERO = &4.APPEND GS_FIELDCAT TO GT_FIELDCAT.END-OF-DEFINITION.SELECTION-SCREEN:BEGIN OF BLOCK BLK01 WITH FRAME TITLE TEXT-001.

SAPABAP面试问题

Answers to some ABAP Interview QuestionsQuestions which I have faced in an interview:1) What is runtime analysis? Have you used this?2) What is meant by performance analysis? Have done anything to improve the performance?3) How to transfer the objects? Have to transferred any objects?4) How did you test the developed objects?5) What is the difference between SAP Memory and ABAP Memory?6) In order to upload Purchase order details, how you handle multiple values for a single field?Eg: Item field may contain no. of values for a record7) What is the procedure you followed to upload the data?8) How did you handle errors in Call Transaction?9) Among the Call Transaction and Session Method, which is faster?10) What are the difference between Interactive and Drill Down Reports?11) How to pass the variables to forms?12) How to create a link between modified form and modified print program?13) What is the table, which contain the details of all the name of the programs and forms?14) How did you test the form u developed? How did you taken print?15) What are Standard Texts?16) What is the difference between Clustered Tables and Pooled Tables?17) What is pf-status?18) Among "Move" and "Move Corresponding", which is efficient one?19) What are the output type and Tcodes?20) Where we use Chain and Endchain?21) Do you use select statement in loop endloop, how will be the performance? To improve the performance?22) In select-options, how to get the default values as current month first date and last date by default?Eg: 1/12/2004 and 31/12/2004Go thru these answers:1) What is runtime analysis? Have you used this?It's checks program execution time in microseconds. When you go to se30.if you give desired program name in performance file. It will take you to below screen. You can get how much past is your program.2) What is meant by performance analysis? Have done3) How to transfer the objects? Have you transferred any objects?4) How did you test the developed objects?I was testing a developed object. There are two types of testing- Negative testing- Positive testingIn negative testing we will give negative data in input and we check any errors occurs.In positive testing we will give positive data in input for checking errors.8) How did you handle errors in Call Transaction?We can create a internal table like 'bsgmcgcoll'. All the messages will go to internal table. We can get errors in this internal table.Below messages are go to internal table. when you run the call transaction. - Message type- Message id- Message Number- Variable1- Variable2- Variable39) Among the Call Transaction and Session Method, which is faster?Call transaction is faster then session method. But usually we use session method in real time...because we can transfer large amount of data from internal table to database and if any errors in a session. Process will not complete until session get correct.10) What are the difference between Interactive andDrill Down Reports?ABAP/4 provides some interactive events on lists such as ATLINE-SELECTION (double click) or AT USER-COMMAND (pressing a button). You can use these events to move through layers of information about individual items in a list.Drill down report is nothing but interactive report...drilldown means above paragraph only.11) How to pass the variables to forms?12) What is the table, which contain the details of all the name of the programs and forms?Table contains vertical and horizontal lines. We can store the data in table as blocks. We can scroll depends upon your wish. And these all are stored in database (data dictionary).Which contain the details of all the name of the programs and forms? (I don't know).13) How did you test the form u developed? How did you taken print?14) What are Standard Texts?16) What is the difference between Clustered Tables and Pooled Tables?A pooled table is used to combine several logical tables in the ABAP/4 dictionary. Pooled tables are logical tables that must be assigned to a table pool when they are defined.Cluster table are logical tables that must be assigned to a table cluster when they are defined.Cluster table can be used to store control data they can also used to store temporary data or text such as documentation.17) What is pf-status?Pf status is used in interactive report for enhancing the functionality. If we go to se41, we can get menus, items and different function keys, which we are using for secondary list in interactive report.18) Among "Move" and "Move Corresponding", which is efficient one?I guess, 'move corresponding' is very efficient then 'move' statement.
