Dear All,

I searched for this issue in the forum, but I did not find any soloution,

I checked
https://archive.sap.com/discussions/thread/3934945
and
https://archive.sap.com/discussions/thread/3344571

I read that could be a problem of language, but I checked again, and my Language is standard, So I do not think that was the problem,

Also I do not think there is a problem with OLAP Connection since my colleauges can access to DataSource!

Can anyone help me about this?
Regards
Sin

What are your preferences? Did you go to Tools > Preferences and is your startup mode BI Platform? See below:

If so you should be logging on to the BI platform when Design Studio launches. Then you should be able to access any OLAP connections that are open to you.
