Symptom
PO Dumps when Ordering it, while the Output Channel is XML and the used Supplier is brand new.
Other terms
Purchase Order, ByDesign, dump, XML, Order
Reason and Prerequisites
If you create a new Seller and define no Communication Type for Purchase Order, and then create a PO whose Output Setting is set to XML, the PO screen will show a dump.
Solution
You may solve this by following this path in UI:
Supplier Base -> Find your supplier -> Edit -> View All -> Communication -> Collaboration ->
Here you must set the Communication Type for Purchase Order to the desired value.
