ResolutionCheck the workbook where the issue occurs to see if there are any complex calculated fields - like fields using LOD (and especially nested LODs!) expressions. Remove the complex expressions (like LOD) and see if the Underlying data loads faster. If it does, this is a workbook performance issue and the workbook should be optimized. For more information, see 6 Tips to Make Your Dashboard More Performant.
CauseQuite often, the real issue is the extremely long time it takes for the Underlying data to appear.
After clicking View Data -> Underlying, the data does appear in the end, but it may take 10-20 minutes to show.
The slowness is down to the very complex query that is sent to the data source when disaggregating the data (when clicking View Data -> Underlying, Tableau composes a SQL query to disaggregate the selected data).
