We are working on a custom report, in which we need to print the details of an invoice. We have the material document number from purchase order history (EKBE) table. I wanted to know from which table i can fetch the invoice details. I don't want to got to BSEG & BKPF, sinche touching these table casuses performance issue. On the otherhand, in MSEG table, no entry found for the material document number (invoice number).
