How to delete inconsistent subreq in PP/DS

Hi Experts,

In Product view  we see a subcontracting requirement (SubReq with category BA)  whihc is out of sync with ERP.

we need to delete the requirement, but when we try to delete manually a info msg disaplyed as 'no valid order selected for deletion'.

We tried to delete using the report /SAPAPO/OM_DELETE_INCON_ORDER provding the GUID info msg displayed as 'Order does not exist, no action required'

But Order is displayed in Product view.

Can any one suggest how to delete inconsistent subreq from Product view.

Regards

Maddy
