We are unable to create a Merge file on any drive on terminal server - error file not found - and I only make a export funktion.
Pleas Help me.
According to my understanding it seems to be you are trying to create a file but facing the error "Error file not found", if it is the issue, have a look at the below link, silent file upload & download
if it is not elaborate the issue in detail
did you try to export an object using the development environment? does this work?
