SRM PO in "Error in Process"

Hello Gurus,

We have a PO with single line item. User cancelled the PO from SRM portal.

Now the issue is PO is in awaiting approval status, after executing the FM "BBP_PD_PO_TRANSFER_EXEC" status on PO changed to Error in process.

When I click "Check" button on PO, getting below error because we dont have a backend PO with this number (Found No PO in ECC)

How to change the PO status to cancelled ?? Can someone help us to resolve this issue??

Thanks in advance.
