- What is the data source you're pulling from?
- Are you using a Custom SQL query?
- Are you using Initial SQL?
My Source DB is a MSSQL-Server.
There is no custom SQL, just connected tables via the connection view.
Some calculated fields (5), nothing more.
Does the server hold more detailed logs?
The Server does have a few logs but I do not even know where to begin looking. You could use a dedicated file search tool and search for
"invalid filter predicate" on the Sever. Agent Ransack is a good tool.
