Payment Advice Number

     Key of a payment advice for which the accompanying open items are to be
     processed.

Use

     Fast selection of items which are listed in a payment advice. Residual
     items and payments on account are created automatically if there are
     differences between the payment advice and the open items.

Procedure

     Enter the number of the payment advice for which you want to select the
     open items. Other selection specifications are ignored when you enter a
     payment advice number.

     If you specify a payment advice number, it is not necessary to enter the
     account number of the customer or vendor. The account number is
     transferred automatically from the payment advice. If you manage a large
number of payment advices in the system, specifying the account can
speed up the process.

You do not have to specify the payment advice number in full. You can
use the asterisk "*" to search for a generic entry.

Using *041, the system searches for all payment advices whose key ends
with the character string "041".

Using *ABC*, the system searches for all payment advices whose key
contains the character string "ABC".

Using MT*, the system searches for all payment advices whose key begins
with the character string "MT".
