Partner function is not working when creating a Purchase Order with ref to a Purchase Requistion, Partner functions maintained in the vendor master are VN, OA & PI.
But OA & PI are not appearing in the PO header partner tab when created with ref to PR.
however it works when i create the PO directly ( without the PR ref )
I am using the same material & Plant for both manual PO & PR to PO.
Any idea what could be wrong .
I have maintained the settings for schema groups for vendor master & purchasing doc in the partner determination.
