QUT1 Sales Quotation row not displaying the OSCN Substitute

Hello,

i am trying to display the OSCN substitute number of an OITM item in a sales quotation when an item is added to the quotatio. but the field is empty when the item is added, even though the OSCN substitute number of that item is existing.

What am i doing wrong? Can this only be done with a UDF and a query?

Any help would be appreciated.

Kind regards

Manuel Ketisch
