How to find work center in REM from the material Documnet number

Hi ,

We want to develop a Z report for the repetitive manufacturing cycle. Please let me know the logic how to get the work center from the material document that is posted after backflushing MFBF tranaction.

I will elaborate it little further. From the material document number that is genearted out of confirmation from that document no how can I find the work center so that we can so show the throughput of each work center.

Please avoid standard transaction of MCRP etc.

Thanks & regards
