I post my problem here:https://community.powerbi.com/t5/Service/Refresh-failed-has-failed-to-refresh-NO-error-message/m-p/1...
I have problem with my scheduling powerbi report. It's worked two days ago but now I get only this message( without error code):
My gateway version: 3000.54.8 (latest)
Szczegóły Typ Uruchom Koniec Stan Komunikat
Last successful run : 8/29/2020
while i refreshing this in powerbi desktop, everything take from 5 to 10 minutes.
Can I find somewhere more accurate error message?Can I do or check something myself? What should I investigating ?
Take a look at Troubleshoot refresh scenarios and create a support ticket for assistance if necessary.
I have read this article before (wasn't helpful). There is no scenarios for my situation (refresh fail a few second after start ~4 sec without any message).
I figured it out, the problem appeared only when in query steps I have at least two "merge queries".Example: "Issued Query" looks like:1step - import csv file2step - merge queries (SSAS source)3step - expand4step - merge queries (Another SSAS source)5step - expand
But how to fix that?
