Documentation

Definition

The link between an incoming payment in FI and an IS-M/SD renewal offer can be determined from the assignment number in the FI line item. This must be noted on a check for posting in order to create the assignment correctly.

A check digit is integrated in this reference number as a mechanism for avoiding transmission errors.

In the standard System, the check digit in the reference number is determined using the function module ISM_CHECKNUMBER_COMPUTE.

If a customer function module is noted here, this is used to determine the check digit. Its interface must correspond to the one for ISM_CHECKNUMBER_COMPUTE.
