That works fine for me. You may check Troubleshoot refresh scenarios.

@v-chuncz-msft Thank you for reply. I checked your link, and did not find anything what could help.

btw last Saturday, automatic scheduled refresh was successfull, but Sunday automatic refresh finished with error (durring weeked source data was not changed it was just test for scheduled refresh).
