I'm quite new to this field, sorry for the newbie question. I guess the solution will be something trivial.
I Created a new, editable field in the Purchase Header table. I want to let the user set it’s value on the Purchase Order Page (P50), more precisely on the Purchase Order Subpage (P54).
I added a new control to the subpage, set its SourceExpr to "PurchHeader.MyNewField".
However, I just can’t update its value, it remains the default 0.00 as I refresh the page (I’ve turned edit mode on). Why? How could I store the new values of this custom field?
Thank you for any help & advice.
