CMD_EI_API Maintain Bapi KNVD Table ( Customer Master )

Hi

I created a report to create customer master data with method maintain_bapi form cmd_ei_api.

My problem is that i can't fill KNVD table with this Method. When i go in XD03 to look a fresh created customer under sales aera data in Documents the message No output created appears.

Did anyone know how to fill KNVD tabel with maintain_bapi?
