COPA获利分析特性或值字段删除

You can delete characteristics and value fields retrospectively from an operating concern that you have already activated. However, you should only use this deletion function for operating concerns that have not yet been used productively. You should also note that some database systems require the operating concern tables to be converted (database conversion) after the deletion has taken place if data had already been posted to the operating concern. Depending on the data volumes involved, the database conversion can take a matter of seconds or indeed several hours. Moreover, you cannot post data or run reports during the conversion. Due to integration, other applications are also affected when data is postedwith an assignment to profitability segments (such as settlement and direct assignment from FI/MM). If the operating concern has been transported to another system (such as the productive system), then the database conversion must also occur in that target system.
Depending on the fields that were deleted, the following tables need to be converted (where xxxx = operating concern):
•Characteristics: CE1xxxx, CE2xxxx, CE4xxxx, CE4xxxx_ACCT, CE4xxxx_FLAG, and CE4xxxx_KENC
•Amount fields: CE1xxxx, CE2xxxx and CE3xxxx
•Quantity fields: CE1xxxx, CE2xxxx, CE3xxxx, CE4xxxx, CE4xxxx_ACCT, CE4xxxx_ACCT, CE4xxxx_FLAG, and CE4xxxx_KENC
Before deleting fields from an operating concern with a large data volume (more that 10 000 records in a table), you should refer to the section "The Database Utility" in the ABAP dictionary documentation. This section describes the database conversion process.
For database systems that do not require conversion (such as DB2 for AS/400, Informix, MSSQL), it can still take a considerable amount of time for the operating concern to be activated.
To delete characteristics or value fields, perform the following activities:
1. Delete the corresponding characteristics and value fields from Customizing in all clients (this
includes forms, reports, planning layouts, and so forth). To locate characteristics and value fields, use the appropriate where-used list in the Customizing Monitor. You can access it by choosing Tools -> Analysis -> Check Customizing Settings. You can jump directly from the where-used list to the relevant Customizing transaction and then delete the appropriate field there.
2. Switch to the screen for maintaining the data structure of an operating concern (Maintain
operating concern).
3. If you need to effect other changes to the datastucture for the operating concern before making
any deletions, effect those changes and save the data structure.
4. In order to be able to select the fields of the data structure, choose Extras -> Characteristics (or
Value fields) -> Unlock.
5. Select the characteristics and value fields to be deleted and remove them from the data
structure with the "Reset fields" function.
6. Reactivate the operating concern. The system starts by checking whether the operating
concern contains any data and whether the fields to be deleted are still being used in any
Customizing settings.
7. If none of the fields are still in use, the system then starts the re-activation. If the operating
concern does not contain any data or does not require the database system to be converted, the tables are activated. You are then able to activate the environment for the operating concern. In this case, the following activities no longer apply.
If the operating concern already contains data, a system message tells you that the database needs to be converted. If you proceed, an activation log appears (at the top of the list).
8. Analyze the activation log. If it only contains error messages telling you to convert the tables, proceed with the next activity.
You must otherwise remove the cause of the errors before the tables can be converted. In this case, you should answer "No" to the next prompt, which asks whether the conversion transaction should start.
9. If you still only receive error messages telling you to convert the tables, choose "Back" and start the conversion.
10. Plan a job for the conversion. A list of the tables to be converted is shown for this. If the tables only contain a small amount of data (less than 10 000 records), then all the tables can be converted in one job. In that case, you can select all the tables.
For larger tables, conversion should take place in several jobs. However, you should ensure that table CE4xxxx (where xxxx = operating concern) is the last table to be converted.
Warning. No other changes can be made to the operating concern during the conversion.
A copy of the table is generated during the conversion. The database system should have sufficient memory available for this copy.
To schedule conversion as a job, use the "Schedule selections" function. You can display the current status of the conversion by selecting the "Refresh" icon. Tables disappear from the list once they have been converted sucessfully. If a conversion is taking a while, it is also possible to leave the transaction. You can then continue the conversion using DB requests -> Mass processing in one of the following ways:
With the job overview. You access this by choosing System -> Services -> Jobs.
Using the database utility transaction. You access this by choosing Utilities -> Database Utility in the ABAP Dictionary menu.
You can use the status function to call up the status of the operating concern during operating concern maintenance. You need to activate all tables after conversion.
11. To analyze errors that have occurred during the conversion, you can use the database utility transaction by choosing Extras -> Logs. The log has the same name as the conversion job: TBATG-date. You can also restart the conversion with this transaction.
For more information on the database utility, choose Help -> Application help while still in the above transaction.
12. Once you have activated all the tables in the operating concern, generate the operating concern environment from within operating concern maintenance.
You can then use the operating concern again.
If you want to transport the operating concern into a different system, see the section "Notes on transport"。
