Table TBACN contains invalid entries

What causes this issue?

The payment program has found an entry or entries in table TBACN which
prevent(s) the program from running.

System Response

The payment program is terminated abnormally.

How to fix this error?

The problem should be determined from the list of probable causes given
below, where appropriate solutions are detailed.
- The payment program searches table TBACN for the last entry used so
that the transaction counters or file numbers are incremented
correctly. The search has found an entry with a date greater than
the run date (system date) of the program. This is theoretically
impossible since the table is updated only by the payment program.
Please examine the contents of TBACN and delete the future-dated
entries. The payment program will then run successfully. Please
investigate how these entries came to be in the table.
