Prebuilt PO integration issue with sequential cancellations

Summary:

Has anyone experienced issues with the prebuilt Purchase Order integration (Fusion → WMS) when using Generate Change Receipt Advice for sequential PO line cancellations?

In our scenario, we were able to cancel one line successfully. However, when attempting to cancel an additional line afterward, the integration sent all PO lines (including the previously cancelled one)from Fusion instead of just the updated ones. This caused errors in the WMS interface since one of the lines had already been cancelled. We were able to reproduce this consistently in test.

Curious if this is expected behavior with change advice processing, or if others have handled this differently without extending the OIC integration.
