new KANBAN PO type defaults confirmation key.
we created a new PO type, copy of NB, that is being generated automatically with KANBAN when container is set to empty.
the problem is that the generated PO, has a confirmation key appearing by default and we want it empty.
I have checked the Purchasing info record AND the vendor master and both do not have the confirmation key set: the field is empty.
is there any other place where I can check? any other source where this field takes the values from?
