Hi Emad,
Since a character '3000' is specified to identify vendor tol group (instead of a blank), master data (fk02) of each vendor for co.code 3000 needs to specify (the vendor tol group -3000) in the co.code segment of payment transaction.
To avoid these type of error, it was indicated before to create a BLANK vendor tolerance group. BLANK is also a character. However every time a vendor is created, you can avoid going and specifying the tol group in the vendor master data. Thanks.
Hope I'm crystal clear with you.
Regards,
Sam
