SAP Business ByDesign

Reproducing the Issue

  1. Go to the Purchase Requests and Orders Work Center.
  2. Go to the Purchase Orders View.
  3. Search and open the Purchase Order ABC (ABC represents the Purchase Order ID).
  4. Click View All.
  5. Go to the Items Tab.
  6. Process Type is greyed out.


Scenario A: the Purchase Order is created from a Purchase Request which in turn is created from a Planning Purchase Proposal, the Process Type of the item will be always To-Stock.

Scenario B: the Purchase Order is created from a Purchase Request which is created from a sales order with items set for External Fulfillment, then the Process Type will be created as third party.

System allows Process Type changes only for Purchase Order items which do not have a predecessor process or if the predecessor process allows it. Creating manual Purchase Orders or adding a new item in an existing Purchase Order, System will allow change of process type.


This is the system expected behavior.
