GR Process for Subcontracting Purchase orders

Hi All,

I am using BAPI (BAPI_GOODSMVT_CREATE) for doing GR for Subcontracting PO.  I am passing the paramters to the BAPI as given in the FM documentation.

Transfer of end product (ordered material of subcontract order) and components

The process happens successfully but the quantity is not getting consumed or reduced from the IM stock ( MMBE) for the material sent to the VENDOR.

The same process if I do using Std SAP T/Code MB01 it does successfully and the quantity also gets reduced from the IM Stock (MMBE).

Please let me know if there is any BAPI to do this or some more paramters needs to be passed to the BAPI.

Thanks and Regards

Rajender
