Help with unfamiliar error message: Duplicate values detected from the data source.
I'm getting the error message below on a table visual in my report. Strangely, this only occurs when a wide data range is selected. My data source is a single Snowflake table. Any suggestions ...
If the table in a dimension table and has a relationship to a fact table, that Id (Key) column can not have duplicates. Or, there is a property of a column to make it the key, it that is the case, no duplicates allowed. You would have to change the source of data.
