PO in ECC- Collective/Individual indicator change not reflected in APO

Hi

It is MTO Scenario and component having value 1(individual requirement) in MRP 4 view. While creating PO we are checking Component availlabilty and if component available, we will change Individulal to Collective option in PO and it should relect appropriately in Product View of APO.

This indi/collective change in PO is not relecting in Product view of APO. Expected result the same PO should shift from MTO segment to MTS segment with new oreder number by overwriting the old one.

Any inputs how to resolve this issue?

Thanks
