Changing IDOC Control Record for EDI inbound Orders Creatiion

Hi,

When I try to process the Inbound orders Idocs file through the GENTRAN EDI System.IDOC's were errored out, because of the Partner function was not defined for the Customer ( Legacy ) ( Type KU ) in the SAP.

Is there any user exit/badi/Configuration to change the Legacy Partner(Customer) to the SAP Partner(Customer) mapping and update the IDOC Control record with the SAP Partner. I am calling EDI_DATA_INCOMING Function module and IDOC_INPUT_ORDERS.IDOCs errored out with Message EO-332 ( Partner function not defined ).

Advance Thanks,

Balaji.
