Subreport not working

[Anonymous]

When I insert a SubReport that's reading from another Report in my workspace, I get this error. 

The report i'm trying to pull from has no issues when I view it independently and other members of my workspace can view it as well.

The only issue happens when I try to pull that nicely working report into a subreport in another file

Hi @Anonymous ,

According to your screenshot, it seems that the subreport is trying to connect to the data source(s) for which the credentials haven't been provided or are incorrect. Could you validate and try the following steps?

• Please make sure all the required data sources have the correct credentials set up.
• Can you view subreport by drillthrough from the main report successfully? Is there any parameter set in the subreport?
• Please try to publish and refresh the subreport again after you configured the correct data source credential and sufficient permission to the data sources
