K3 采购订单选单时，换供应商的问题

采购部门有这样一种操作，如果是有A供应商的申请单过来，需要从B供应商处购买，由于物料较多，先做一张订单，然后在这张订单上去增加，进行选单操作，但选单出的申请单数据，都是B供应商的申请单，而不是A供应商的数据。

跟踪语句出语句如下

Select top 100000 t15.FName,v1.FTranType as FTranType,v1.FInterID as FInterID,u1.FEntryID as FEntryID,u1.Fauxqty as Fauxqty,t11.FQtyDecimal as FQtyDecimal,t11.FPriceDecimal as FPriceDecimal,u1.FSecCommitQty as FSecCommitQty,u1.FSecQty as FSecQty from POrequest v1 
INNER JOIN POrequestEntry u1 ON     v1.FInterID = u1.FInterID   AND u1.FInterID <>0 LEFT OUTER JOIN t_Department t4 ON     v1.FDeptID = t4.FItemID   AND t4.FItemID <>0 LEFT OUTER JOIN ICMO t5 ON     v1.FSCBillInterID = t5.FInterID   AND t5.FInterID <>0 LEFT OUTER JOIN t_Submessage t17 ON     v1.FMRP = t17.FInterID   AND t17.FInterID <>0 LEFT OUTER JOIN t_Emp t8 ON     v1.FRequesterID = t8.FItemID   AND t8.FItemID <>0 INNER JOIN t_ICItem t11 ON     u1.FItemID = t11.FItemID   AND t11.FItemID <>0 INNER JOIN t_MeasureUnit t14 ON     u1.FUnitID = t14.FItemID   AND t14.FItemID <>0 LEFT OUTER JOIN t_Supplier t15 ON     u1.FSupplyID = t15.FItemID   AND t15.FItemID <>0 LEFT OUTER JOIN t_MeasureUnit t16 ON     t11.FUnitID = t16.FMeasureUnitID   AND t16.FMeasureUnitID <>0 LEFT OUTER JOIN t_MeasureUnit t500 ON     t11.FOrderUnitID = t500.FItemID   AND t500.FItemID <>0 LEFT OUTER JOIN t_MeasureUnit t502 ON     t11.FSecUnitID = t502.FItemID   AND t502.FItemID <>0 LEFT OUTER JOIN t_Submessage t103 ON   v1.FBizType = t103.FInterID  AND t103.FInterID<>0 LEFT OUTER JOIN v_ICPlanCategoryEntry t9521 ON   v1.FPlanCategory = t9521.FID  AND t9521.FID<>0 where 1=1 AND (     
ISNULL(t15.FName,'') LIKE '%顺%'
)AND ((   (u1.FSupplyID=208873 OR ISNULL(u1.FSupplyID,0)=0) and  (v1.FStatus IN (1, 2) AND u1.FQty>u1.FCommitQty AND u1.FMrpClosed=0 AND v1.FBizType = 12510)) AND ((v1.FCheckerID>0)))

其中条件有“ (u1.FSupplyID=208873 OR ISNULL(u1.FSupplyID,0)=0)”，这个就是供应商的代码条件

经过查询和分析，认为其应该来自于选单关联表ICSelbills
在https://www.cnblogs.com/caipanlong123/p/11065784.html
中FSELTYPE=1的这样的描述
FSelType：目标字段的类型；0表示单据分录字段，2表示单据头字段，1表示该目标字段的当前值将会作为选单序时簿的过滤条件；

于是

delete ICSelbills   where FFieldName='FRequestInterID' and FDstCtlField='FSupplyID' and FSelType=1

并做好备份

--INSERT INTO ICSelbills (FID, FFieldName, FDstCtlField, FSelType, FDK, FColName, FName, FTableName, FTableAlias, FAction, FROB, FAllowEdited)
--VALUES('P02','FRequestInterID','FSupplyID',1,1,'','FSupplyID','PORequestEntry','u1','',0,0)

再操作时

可见“ (u1.FSupplyID=208873 OR ISNULL(u1.FSupplyID,0)=0)”的供应商条件已经没有了。

在程序中选单也能过滤出任务供应商的申请单了。

另外后面的和一个条件来自于ICClassLink
