How To Fix V1556 - PO type is missing: Purchase requisition will be deleted/not created

SAP Error Message - Details

• Message type: E = Error

• Message class: V1 - Verkaufsbelegbearbeitung

• Message number: 556

• Message text: PO type is missing: Purchase requisition will be deleted/not created

What causes this issue?

The system should create or process a purchase requisition although the
current schedule line category '&V1&' does not contain a purchase
order. This message appears, for example, if, while creating a sales
order, you changed the item or schedule line category for an item with
a purchase requisition so that the item no longer needs a purchase
requisition. In this case, the message is just to inform you that the
existing purchase requisition will be deleted.
The message can, however, also appear if there are any errors in
Customizing. Possible problems could be:
Schedule line category '&V1& should be valid for the purchase
requisition but a purchase order type has not been maintained.
The schedule line category '&V1&' has been determined incorrectly for
this item.

System Response

The system deletes the existing purchase requisition for the schedule
line. It does not create a purchase requisition for the schedule line
if one doesn't already exist.
