same pbix on power bi report server scheduled refresh fails and succeeds

Hi

 

I deployed some pbix reports on PBIRS. I created scheduled refresh. My problem is that they sometimes fail and sometimes succeed. I am talking about the same pbix file. The same pbix file fails and succeed. That is why I think it is something about PBIRS. If it was about the pbix file, it wouldn't had refreshed at all.

 

Also, when I go to

Manage => Scheduled Refresh => Refresh Now

they successfully refresh, some from the first time, some from the second, third or fourth time

 

I mainly have 3 errors

 

1- Unable to combine data error. 

Exact error syntax

ErrorCode 1055784932 Unable to combine data: xxx references other queries or steps, so it may not directly access a data source. Please rebuild this data combination

 

2- Deadlock victim

Exact syntax

ErrorCode 0 Transaction Process ID 71 was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction

 

3- Report Server Database Unavailable

Exact syntax (there are 2 actually)

3-1- ErrorCode 1056505856 COM error: Microsoft.BIServer.HostingEnvironment, ReportServerDatabaseUnavailableException
3-2- ErrorCode 1056505856 COM error: Microsoft.PowerBI.ReportServer.ASEngineManagedRoot, ReportServerDatabaseUnavailableException

 

So why does that happen ?

 

And is there a way to tell PBIRS to keep refreshing until it reaches a success, just like I do but somehow programmatically ?

 

Thanks
