Sub Contracting Challan

Hi All,

In Subcontracting process first we are sending the raw material to sub contracting vendor with Sub Contracting Challan. Now subcontrating Vendor return the raw material due to quality problem. So, please suggest what process we have to do in SAP ? Because we have to closed the sub contracting challan and stock of raw material should come under unrestricted use.

Thanks in Advance.....
