3102040 - After upgrade to 7.50 SP21 in PI, Concur integration is not working

You have some Concur Integration scenarios running in your systems through a middleware (Process Integration/Orchestration).

After an update in SAP PI/PO system to release 7.50 Support Package 21, the Concur integration starts to fail in the ECC system with some errors.

If you capture an XPI Inspector trace (with HTTP Client Full Dump selected) while reproducing the issue, you will be able to see that all the PI/PO requests sent to Concur are either failing with HTTP 403 or HTTP 401.
