BOM LINK ISSSUE

We send semi finished component, say Y, to vendor he at his end adds bronze material along with machining and sends us the semi finished component, say Z , using a PO.

We CANNOT send component Y to get Component Z on 57F4 subcontracting challan as there is SIGNIFICANT material addition at Vendors end(This is as per Excise Dept instruction).Here we sell component Y to Vendor and on new PO we do GR of component Z.

Now our problem is to get qty required of component Y, P and Q as there is no BOM link as link between component Z and component Y is missing

Hence we are unable to get qty of component Y ,P ,Q through MRP run

BOM STRUCTURE IS AS BELOW

Component A-- ->Component B -> Component Z >Component Y -- >Component P -->Component Q

Please help
