I'm currently using LSMW(IDOC), message type PORDCR1 to create Purchase Order. I've looked through the relevant OSS Notes: 420331 on how to assign the package number to link line item, service line and service account assignment.
I'm aware that a "header service line" will have to be created to link multiple services to 1 line item. However, I do not want to have to assign this header line in my data but have it programmed to be assigned during the LSMW upload process. Is there any way that I can append this additional header service line in the LSMW progamme?
I do not have a developer's key, hence I cannot create an ABAP programme to add this logic.
