2450031 - Connection test failed for RFC destination CALLTP_<OS>


The testing of the RFC destination CALLTP_<OS> fails in SM59. STMS procedures which use this RFC destination, on the other hand, seem to work normally.

The usual scenario is the following:

  • The affected system has more than one instance;
  • Sometimes, while testing the RFC destination CALLTP_<OS> from transaction SM59, the result will be "user XXX is not allowed to start the program".
  • You notice that the path specified for the TP (at the RFC destination's properties in TCODE SM59) seem to change from time to time from something like:


to something like:


Or even to:


  • It is specifically at these occasions that the destination testing will fail.

It is important to stress that this document handles only the scenario where the "Connection Test" operation fails.
