Goods Cancellation/Returns

We are on SRM_SERVER 550, SAP 4.7 backend and have configured ECS.

The confirmation workflow WS10400010 (No Approval) is activated.

While testing the application, I am unable to create Cancellation or Returns for the confirmed line items which are not invoiced.

On selection of u201CDisplay/Process Confirmationu201D from the drop down list and searching the POs, the selection overrides to the default u201CConfirm Goods Receiptu201D.

Kindly let me know if there are any settings need to be done so as to activate the Goods Cancellation or Returns.

Thanks,
