More information
You are joining your feature layer with more than one joined table, which may potentially result in poor drawing and query performance. You can test your map to see if display performance will be acceptable.
If your application warrants the use of multiple joins, you can choose to mark this warning as an exception to avoid receiving the warning next time you analyze the document. Beware that the resulting map may draw more slowly.
