invoice discount in posted invoices

Hello. (Attain 3.01B) Does somebody know why the fields “invoice discount calculation” and “invoice discount value” (Sales Header) are not copied into the Sales Invoice Header when the Sales Order is posted (there is only “invoice disc. code”) and pressing F9 Attain calculates the shown invoice discount from the lines. Can I copy these two fields to the posted invoice header (copying the content to two fields over 50000 that i’ll create in both tables)? It’s surely not a very nice solution, but will it work? (or will I create disfunctions to other features, i.e. is there some reason for the invoice discount being recalculated) Edited by - mlml772 on 2002 Mar 15 09:17:26
