When flexible workflow is activated - Ariba Confirmation for PO is not getting updated in S4.

Hello Experts,

We have implemented a flexible workflow for certain user IDs in our SAP system. And for the remaining user IDs - auto PO release strategy is getting triggered. However, once the PO is confirmed in Ariba - the confirmation details are not updated in the order.

And when deactivate the flexible workflow - the Ariba confirmation gets updated in the PO.

Please advise on how to solve this issue.
