Subcontracting Scenario for serialized, Recursive Material.

Hello,

• We are working with SAP R/3 EHP6 enhancement package, IS-Utilities activated.(No DIMP function activated.)
• We are working with subcontracting scenario for Serialized Material RECURSIVE BOM.
• We have to give subcontracting PO to vendor with recursive material ( Material number and Serial Number same at time of return.)
  Recursive component sent to vendor against PO created above with Mvt 541.The material will be taken back to inventory instead
  of any PM order/ Refurbishment Order consumption, so that same can be tracked through inventory reporting for further utilization at different sites.
• Trying to create GRN, using Mvt 101, system throws an error message " Material serial number already entered", this is because
  system trying to post consumption for recursive component with Mvt 543.
• Please advice how to handle such scenario of serialization, subcontracting, recursiveness.

We have alternate option of not creating PO and just send the recursive material to vendor using Mvt 541 and use report
MBLB to track the material at vendor , and take back to stock with Mvt 542(No taxation scenario) , once repaired and received.
We are using valuation types for material for identification of faulty and repaired material.

Thanks,

Ankush
