+++++++++++++++++++++++++++++++++++++

Is that an issue with the RFC_* connection ID /password or something to do with Version compatibility.?Do we need to upgrade OneIM to later versions or there is an alternate solution?

A solution provided (number of the fix is #34095) in one of the forums for a 9.2 V system.  But that is for later versions and possibly happens after the connection is established. Any suggestions are helpful.

Thanks
