Slicer: limit list to top X count?

I have a slicer used for customer accounts.


The user enters a customer account ID in the search and it works great.


HOWEVER, there is also a region selector on the page.


Normally the report loads with the region selected and or the user will change the region.


IF the user clears the region, too many customer account IDs come back to the slicer and it causes delays.


Is there anyway to make a slicer only show TOP X?  Basically I the user to always pick a region and not clear it out, or when they do clear it, I don't want the entire report to run trying to load all the data.





EDIT: I supopse a cascading dependency would work too?  Maybe I could require at least one region be selected so that when they clear the page, nothing happens until at least 1 region is selected?  Can that be done?

Thanks, in this case though it isn't a direct query.


It is a tabular model, it just has a LOT of customers in it 🙂

Hi @OneWithQuestion


it works also if you're not in direct query
