I have a scenario where I want to filter a table using two seperate slicers.
In this scenario, I expect that 'Select All' on the low level slicer should only select those made visible by the high level slicer???
Wrong - using 'Select All' PBI opens up all items regardless of whether another filter may hide them. I can click indivual items in the lower slicer to get the desired result but what's the point of that - there could be many clicks however when I really just want one - I suppose I need a way to 'Select All Filtered'?
The inherent visua does not provide this functionality - is there another out there that does?
You can modify interaction to only allow high level slicer to filter on low level filter.
If you apply filter on high level filter, these filter effect will also appears on other one, the low level filter not affect other one.
In addition, you can also turn on high level filter effect on page or report level filter, low level slicer will display items who suitable page/report level filter.
I guess your the two columns used in these two slicers are from different tables.
If this is the case, check the relationship between these two tables, and make sure the Cross filter direction are both. This should make the lower level slicers only show values visible by the high level slicer
