SAP Note 11295 - Client dependency transceiver.

Symptom

Overwriting the interface files of the transceiver when using multiple
clients, for example client 000 writes into the interface of client 001
and vice versa, providing the subsystems are installed on a common
hardware.

Cause and prerequisites

Table TXCOM is not client-dependent.

Solution
If several subsystems must be operated in one communications channel,
it is necessary that each subsystem has its own hardware available.
By means of transaction CD72, it is possible to define different
subsystems client-specifically.

Key word: Transceiver
