Hi Pascale,
The ABC This is in case that you want a UDF field in the customer master data saying for example Project mandatory Y/N. In this case you would have a flagin the customer saying if the project is mandatory. Then all the customers thatyou wanted to have a project mandatory should have a "Y" in the master data.
If you don't want to use the UDF just change to
IF @OBJECT_TYPE ='13'AND
(@TRANSACTION_TYPE = 'A' or @TRANSACTION_TYPE = 'U')
BEGIN
IFEXISTS(
SELECTdocentry from OINV T0 inner join INV1 T1 on T0.DocEntry = T1.DocEntry where T0.CardCode In ('CUS001', 'CUS002', 'CUS003')and T0.DocEntry = @LIST_OF_COLS_VAL_TAB_DEL and (T1.Project IS null or T1.Project = ''))
BEGIN
SELECT @ERROR=1,@ERROR_MESSAGE='the project is mandatory for this customer'
END
END
Hope it helps
