No release strategy for a PO created in reference to a Contract

Hello,

I did search the forum but couldn't find exact answer. System doesn't triggers a release strategy, when a PO is created with reference to a contract, which is already approved. This is a standard SAP function, which is logically correct.

A release order (PO), shouldn't be approved again, when the reference contract is already approved.

I have below questions,

1. Is there any SAP KBA or note which explains this function? I did search SAP OSS portal, but couldn't find any related note or KBA.

2. Is it possible to trigger a release strategy for a PO in above case?

Appreciate your help on above questions. Thanks in advance.
