I need a Business Transaction Event or user-exit on save of a FI-document (transaction FB01, or any other possible posting). The trick is, that I must have an internal FI-document number (field BKPF-BELNR) already assigned to the document and to use this number for my purposes.
I tried to use some of the BTE-s (1110, 1120, 1130, 1050 and 1060) without success - the belnr is not yet assigned when the system passes to this customer exits.
Could someone help me with this please? The important thing is - I need BELNR already assigned to the document. All these in 4.6D enterprise environment.
Thanks in advance.
