We are trying to use the SAP pro forma invoice add on available from the SAP Store for Business ByDesign.
We purchased it from the store, and scoped it into our system, and see the button where we are expecting to use it in Outbound Logistics -> Outbound Deliveries. However, when we click the button to generate the pro forma invoice, we receive an error message (please see attached).
Can anyone provide information on where we specify the form we want the pro forma invoice to be generated on?
