Errors in the Metadata Manager in Apps
By Joyce Zhou - Updated January 11, 2017
In apps, users encounter an error message reporting that an error occurred when loading database role from file.
The error is coming from Analysis Services. SSAS depends on the file system and for some reason, the files appear to be getting corrupted on a regular basis.
Please restart SSAS server, and then re-deploy the application. If it doesn’t solve the issue, please install the latest CU of SQL.
