Copy Control for Billing Documents turns to zeros Reference no.(VBRK-XBLNR)
I think I have a problem with copy control, but I don't know where, so I would like you guys to help me find it.
When I create a Return Billing Document, with reference to a Delivery (Return), the field 'Reference no.' comes from the Sales Order (Return) correctly, where it is defined as required (obligatory). But when I save this Billing Document, the 'Reference no.' turns to zeros ('0000000000000000').
What might be wrong in my configuration? I'm trying to find but I had no success yet.
