Hi All
I'm creating invoices with MIRO transaction.
I want to change some document items of FI document related to one invoice, assigning the vendor number of header invoice to the field bseg-lifnr created in FI document.
I have tried with BTEs, substitutions, exit LMR1M001, BADI Invoice_Update and Enhancement in MRM_INVOICE_PREPARE_AND_POST.
I can't find the way to change this field of the FI document during posting with any of these techniques.
Thank you in advance
