Failed to connect to backend system. Check your system definition and user privileges.

Hi Experts,

I've got a problem with a BW-Query (not) running in a VC model.

I've a big model with many rfc-bapis and some BW-Queries. One of the BW-Queries has been changed and now doesn't work anymore with "normal" user settings! The other queries are running. There is no permission-problem on BW-side.

I checked the user mapping (user-ID and password). They are exactly the same.

I did also like shown in [https://www.sdn.sap.com/irj/sdn/wiki?path=/display/vc/failed%2bto%2bconnect%2bto%2bbackend%2bsystem].

Does anybody has an idea? This problem is very urgent...

Thanks for your response
