Stored Procedure based on Row Level

Question

Hi
I have created a Stored Procedure that works perfectly off the Header Level but not on the Row Level, the query is as follows:
IF @transaction_type='A' AND @Object_type = '13'
BEGIN
--AR Invoice
IF EXISTS (SELECT T0.DocEntry FROM [dbo].[OINV] T0 WHERE T0.Project ='0' OR T0.Project IS NULL AND T0.DocEntry = @list_of_cols_val_tab_del)
BEGIN
SET @Error = 10
SET @error_message = 'Please select Project Code under Accounting Tab > BP Project'
       END
END
Now I want to base it off Table - INV1, Field - Project, when executing it in SQL Server all seems good but once running in SBO the Stored Procedure does not trigger causing the user to bypass selecting a Project from the Project Field which is Mandatory; could this be down to T0.DocEntry as there is a DocEntry in INV1 and none in OINV?
Any suggestions will be appreciated.

Try this one:
IF @transaction_type='A' AND @Object_type = '13'
BEGIN
IF EXISTS (SELECT T0.DocEntry FROM dbo.INV1 T0
WHERE (T0.Project ='' OR T0.Project IS NULL) AND T0.DocEntry = @list_of_cols_val_tab_del)
Begin
SET @Error = 10
SET @error_message = 'Please set Project Code on every line !'
End
END
