Hello CB,
Thank You very much. There was multiple fold - We have Full Unicode mode RFC connection and customizing for WWI .
This issue was resolved via -
Re installing PDF reader on WWI serve by Downgrading to 9.2 version as oppose to XI
Changed the RFC which was not reading the error file from WWI server
Changed some more setting at D COM
We could not understand why PDF version was an issue but this seems to be working now.
Thank You for your help.
