I host SSAS on Azure VM, connect SQL server as Data source in same VM. install and develop report with Power BI desktop in same machine.
I install the Power BI on promised gateway in order to publish to my account. After setup the gateway setting in PowerBI, all thing looks well (report green connected message), but when click datasets, it shows an error said: ''there was a data source access error. Please contact the gateway administrator".
Then I try directly use "Get Data" to connect to SSAS, it shows error following:
How can I debug this problem?
I search a lot and think it might need to setup "Map user names".
I don't understand this function because the two options 'Effective User name'/'CustomData' are so comfusing and I don't know what should to be `Replace`d?
when I try setup the 'CustomData' with anything, there will show another Error:
The following system error occurred: There are currently no logon servers available to service the logon request
I have already spend 8 hours on this problem, and now I think I have already try all the way I can, is any one can help me with the problem? or tell me know to trace with above message.
P.S. Currently in my local machine, I use windows main account to login to SSAS, it looks like 'TEST\abc', and the local SQL server using the same account to login too (also setup SQL account login).
