Purchase order does not allow to create a PO for Site related to a CPA when CPA has a different Site

Summary: We are converting PO from EBS, and some PO lines are associated with CPA. When PO Line with CPA is associated with a Supplier Site, system does not allow to pick that Supplier Site. System is checking the supplier Site from the CPA.

In the CPA we turn on the Allow ordering from unassigned sites, but system ignore this configuration.

Example:

PO for supplier ODP, Supplier Site AAA

CPA for Supplier ODP, for the Site 123

During the conversion the system does not allow to pick the Supplier Site AAA
