transmission number that does not yet exist in table <LS>TRNSM</>
(Field: <LS>TRMNO_EXT</>, external transmission number). Make sure that
the transmission number is unique for the following parameters:

Restart inbound processing (in the background).

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

If you do not want processing to terminate as a result of the external
transmission numberconsistency check, set <LS>automatic processing
