Can values returned by a lookupset be used for interactive sorting or a report filter?

Question

I have a report that uses multiple stored procedures. I am using the lookupset function to return the values, then I sum the values with custom code, and have them display all into one tablix. However I can not figure out how to use interactive
sorting or a report filter with values returned by the lookupset function.
My question is:
Can you use values returned by a lookupset for interactive sorting or a report filter?
Thanks!

Hi WGiff,
Based on my understanding, you want to perform interactive sorting or filter for the values which come from multiple datasets.
In Reporting Services, LookupSet()function is used to retrieve a set of values from the specified dataset. So in your scenario, we should use Lookup() function to retrieve values from specified dataset, then perform interactive sorting or filter.
As we tested in our environment, we retrieve values using Lookup() function form datasets, then sum these values with custom code. After enable interactive sorting or filter for these values, we can get expected results.
1. Add custom code below in Report Properties.
Public Shared Value as Integer=0
Public Shared Function GetValue(Item as Integer) as Integer
value= value + Item
return Item
End Function
Public Shared Function GetTotal()
Dim a as integer
a=value
value=0
return a
End Function
2. Enable Interactive Sorting.
3. Add filter within the group.
If you have any question, please feel free to ask.
