Issue with Idoc WMMBXY

Hi to all

I have the following scenario:  I want to create a Material Document from SAP ECC to another system SAP ECC. This material document is created through MIGO transaction code.

I am using the Idoc WMMBXY to pass this informacion, with the Type WMMBID02, and Process Type WMMB. In the transaction code WE41, the Process Type WMMB has the FM  L_IDOC_INPUT_WMMBXY

With all this parameters the Idoc isn't work.

Please help me about this issue.

Thank you very much

regards
