Purchase order type not defaulting.

[MO_Lee]

Purchase order type not defaulting when converting it from Purchase requisition that's driven by MRP.

I'm trying to convert the Purch Requisition to a specific Purchase order (STO order type), but the system is picking some random PO Doc type. 

How do I make the PO Doc type default for a specific Purchase Requisiiton?

Appreciated your help.

Hi,

If its intra company STO with item category U, I would suggest to remove the allowed item category U from all other document types other than the expected STO document type from the path: OLME - Define Document Types for Purchase Orders - Allowed item categories. Also maintain only one item category allowed (U) allowed for the STO doc type and test the scenario.

In addition, refer the notes: 2620578 - Default item category based on PO document type 

2166635 - ME57 non ALV: Determination of the PO document type 

3108114 - Default document type is not used when creating PO via ME59N
