Problem in PO Closing

Question

Closing of the Purchase Orders
The change is to be made for the field  ELIKZ Delivery completed indicator. All the open purchase orders are to be closed.
But the material group of the materials has been changed so the system is issuing the message  Material group the material has been changed. And system is not allowing closing the purchase orders.

Answer 1

Hi,
Check the following data with respect to material master.
When changing the material group of a material that is already being used by the purchasing department, you should note that:
The purchasing statistics show how much of a material group has already been ordered. Unitl the change is made, the material is managed under the old material group and therefore the old material group statistics are updated. From the moment the change is made, the new material group's statistics are updated.
Some purchase orders may derive from contracts with item categories referring to material groups. If this is the case, the material cannot be used after the change has been made.
Every purchase requisition is allocated to a release strategy that can depend on the material group. A new release strategy may apply to a new material group. Purchase requisitions that were created before the change are subject to the old strategy; purchase requisitions that were created after the change are subject to the new strategy.
