Deletion of SRM-PO which is in Ordered Status in Portal(EBP) cannot be done

Hi Folks,

There is a problem happening for us in Extended Classic Scenario of SRM. We are using SRM-5.0 solution and ECC-6.0.

The PO is ordered and the information has gone to vendor. We want to delete the PO completely in PRD.

I have read that we cannot delete the PO in header level.

But i cannot able to delete the PO in item level too.

I have the purchaser role and the delete button is inactive / greyed out completely for that particular PO.

Can anybody please let me know in which all tables i need to delete the PO in SRM(backend) and also in R/3(dedicated to SRM).

Thanks and Waiting for the help,

Ajantha.
