I want to create the proforma Invoice for Service Material w.r.to Order.
I have maintained the copy controls in the VTAF and also maintained the item category as "TAD" at Item level.
I have tested by maintained the Billing relevance in Item category"TAD" as "D","Blank","L" etc.
I have also maintained the billing type in sales document type as "F5" to pick the billing type as F5 default.
Still system is throwing an error stating " ITEM CATEGORY TAD IS NOT RELEVANT FOR PROFORMA INVOICE".
Kindly help me where I am doing mistake.
