金蝶kis专业版有部分账套打开后提示无法建立数据连接

金蝶kis专业版有部分账套打开后提示无法建立数据连接，或者
保存凭证时弹出对象名"VoucherEntry 无效
问题原因：由于数据库中t_voucherentry 表中丢失索引导致
解决方法：
先把帐套备份后，请参考如下方法处理：
第一步：在SQL查询分析器中选择问题帐套，备份表t_voucherentry 数据到temp1 表（直接在坏的这个数据库里面执行下面这个语句就可以） Select * into temp1 from
t_voucherentry（说明意思：在数据库里新建temp1这张表并且把t_voucherentry里面的数据导入到temp1里面）
第二步：删除t_voucherentry 表，（执行下面语句）
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[t_VoucherEntry]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)drop table [dbo].[t_VoucherEntry]
第三步：创建一张t_VoucherEntry表（执行以下语句即可）
CREATE TABLE [dbo].[t_VoucherEntry] ( [FBrNo] [varchar] (10) COLLATE
Chinese_PRC_CI_AS NOT NULL , [FVoucherID] [int] NOT NULL , [FEntryID] [int] NOT NULL , [FExplanation] [varchar] (255) COLLATE Chinese_PRC_CI_AS
NULL , [FAccountID] [int] NOT NULL , [FDetailID] [int] NOT NULL , [FCurrencyID] [int] NOT NULL , [FExchangeRate] [float] NOT NULL , [FDC] [smallint] NOT
NULL , [FAmountFor] [money] NOT NULL , [FAmount] [money] NOT NULL , [FQuantity] [float] NOT NULL , [FMeasureUnitID] [int] NOT NULL , [FUnitPrice] [float] NOT
NULL , [FInternalInd] [varchar] (10) COLLATE Chinese_PRC_CI_AS
NULL , [FAccountID2] [int] NOT NULL , [FSettleTypeID] [int] NOT NULL , [FSettleNo] [varchar] (40) COLLATE Chinese_PRC_CI_AS NULL , [FTransNo] [varchar] (100) COLLATE Chinese_PRC_CI_AS NULL , [FCashFlowItem] [int] NOT NULL , [FTaskID] [int] NOT NULL , [FResourceID] [int] NOT NULL) ON [PRIMARY] GO
ALTER TABLE [dbo].[t_VoucherEntry] WITH NOCHECK ADD CONSTRAINT
[PK_VoucherEntry] PRIMARY KEY CLUSTERED ( [FVoucherID], [FEntryID] ) ON [PRIMARY] GO
ALTER TABLE [dbo].[t_VoucherEntry] ADD CONSTRAINT
[DF__t_Voucher__FBrNo__4D5F7D71] DEFAULT ('0') FOR [FBrNo], CONSTRAINT [DF__t_Voucher__FDeta__4E53A1AA] DEFAULT (0) FOR [FDetailID], CONSTRAINT [DF__t_Voucher__FQuan__4F47C5E3] DEFAULT (0) FOR [FQuantity], CONSTRAINT [DF__t_Voucher__FMeas__503BEA1C] DEFAULT (0) FOR
[FMeasureUnitID], CONSTRAINT [DF__t_Voucher__FUnit__51300E55] DEFAULT (0) FOR [FUnitPrice], CONSTRAINT [DF__t_Voucher__FAcco__5224328E] DEFAULT (0) FOR [FAccountID2], CONSTRAINT [DF__t_Voucher__FSett__531856C7] DEFAULT (0) FOR [FSettleTypeID], CONSTRAINT [DF__t_Voucher__FCash__540C7B00] DEFAULT (0) FOR [FCashFlowItem], CONSTRAINT [DF__t_Voucher__FTask__55009F39] DEFAULT (0) FOR [FTaskID], CONSTRAINT [DF__t_Voucher__FReso__55F4C372] DEFAULT (0) FOR [FResourceID] GO
CREATE INDEX [ix_VoucherEntry_1] ON [dbo].[t_VoucherEntry]([FAccountID]) ON [PRIMARY] GO
CREATE INDEX [ix_VoucherEntry_2] ON [dbo].[t_VoucherEntry]([FCurrencyID]) ON [PRIMARY] GO
CREATE INDEX [ix_VoucherEntry_3] ON [dbo].[t_VoucherEntry]([FDetailID]) ON [PRIMARY]GO
第四步：插回凭证表中的数据 Insert into t_voucherentry select * from temp1
第五步：删除这张临时表temp1 命令 Drop table temp1
完毕。

已经测试可以解决。
