After having attempted to get the Enterprise Gateway working, I hit an error which I posted about here DM_GWPipeline_Gateway_ImpersonationError.
Having no success with the Enterprise Gateway, I then installed the Personal Gateway. It appears to have installed and configured succesfully. However, when I then set up a scheduled data refresh, the scheduled refresh fails only returning the following error:
"Processing Error: transfer service unknown error"
Has anyone encountered this before? Is there anyway to reveal a more descriptive error? Any thoughts/suggestions are greatly appreciated as one way or another I need to get a refresh mechanism working without manual intervention.
Best Regards,
CP
Did you ever resolve this ? As i too just got the exact same error...but not on data refresh.
it occurred whilst 'add data source' as admin in 'manage gateways" enterprise version...
ie adding a SQL server data source to our enterprise gateway
Exact error is :
Error Code: DM_GWPipeline_Gateway_ImpersonationError
