I'm an ABAPer and I've been asked to create a new LSMW which would allow users to upload vendor invoices with several line items. I've done some searching and found program RFBIBL00 which only seems to support accounting documents for clearing/posting so isn't suitable. Someone else suggested using BAPIs BUS2042 but I can't see how I can enter several line items using this.
Can anyone suggest a standard object/BAPI which I can use or tell me how to create a recording to do the same thing?
Any suggestions welcome.
