I am trying to relate tables F0911 with F7601B and F76101B by using F0911.GLVINV = xxBNNF (invoice number) and F0911.GLAN8 = xxAN8V (supplier code) with the aim to bring invoice details such as SERIES (FHBSER) and INVOICE TYPE (FHDCT), for example. However a few lines do not contain F0911.GLVINV...
