We have recently upgraded BW 3.5 to BI 7.0 and installed SAP GUI 710.
When we try to open queries using old 3.5 BEx Analyser, we are getting error ' RFC Error Received '.
strange thing is, it is not happening with all the users. For some users it is working fine and for some users they are getting this error only on first instance when they login after upgrade and this error is not comming from second time onwards with out implementing any corrective actions. Some users are still getiing this error even on second time when they login after upgrade.
We are prety much confident that the authorisation is not an issue here. Not sure about the GUI.
Pls help me to understand the possible resons for this error and how we can fix it.
