When running a transaction detail report, the description for invoices is the name of the vendor or individual paid. Sometimes more information is needed. For example, airline tickets purchased through Superior Travel are charged to American Express. The transaction detail description tells you that American Express was paid, but gives no information about who the airline ticket was for.
Use report FZAINV016 – Paid Invoices by Invoice Transaction Date in Finance/Department. Enter a date range, AMERI0028 for the vendor ID and your department code to see travel charges paid through American Express. Enter a % in the index and account code parameter if you are not specifying either. The invoice description will give some additional information about the charges.
