I am trying to bill a order with a TAB item, but when I select a proforma for Order F5, II get the following message : Item category TA TAB cannot be invoiced with billing type F5....
I tried to move the billing relevance for A to E (Delivery-related billing document to Relevant for pro forma)for my item category (TAB Indiv.Purchase Order)
Sales Distribution / Sales / Sales documents item / Define item categories
Is it a good option ? Do I have to do something else ?
