问题：金蝶kis专业版16.0保存凭证时提示 无法建立数据库，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，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）

第二部，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]
 第三部，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
   第四部，插回凭证表中的数据
    Insert into t_voucherentry select * from temp1
    第四，删除这张临时表 temp1
    Drop table temp1

完毕。亲测
