SSRS with DAX - parameters multivalue vs total element

Question

Hi all,
I'm using SSRS on top of a SSAS tabular model to create intuitive dashboards for management department.
One thing I'm struggling with is the lack of a "total" on parameters. What I'm doing is, based on the fact table, I create the datasets that will feed each parameter, so it only has the dimension members available on the fact table. That is fine
performance wise, you only have 1 element and it renders very quickly.
For a management perspective at a higher level it is important to view the totals to have the big picture of the information. In my project we are in a University, so I have the parameters Year, school (there are several schools in the university campus)
and the course (computer sciences, math, statistics, etc).
At first glance, if I'm a course coordinador I want to pick my course and have a global view, and I'm achiveing that, but imagine now, that I am the school coordinator, or the university coordenator.
I want to see the aggregate values by all courses or by all schools.
In my view I have 2 ways to do this and I come from a tradition cubes background:
1 - I would use the all element the cubes hierarchy have on each attribute
2 - I would use multivalue parameters with StrToSet (worse performance)
Using DAX what is your approach?
Best regards

Hi AsifMehmood,
Per my understanding you have create an SSRS report with SharePoint list, now you don’t know to create the distinct parameters by using CAML query,  right?
For the CAML language doesn’t have any reserved word (or tag) to set this particular filter to remove duplicate results, but we can use the custom code to do this function. I have tested on my local environment and we can do that by create one hidden parameter(Param1)
to get all the values from the fields which will  add the filter and then create another parameter(Param2) to get the distinct values based on the Param1, we use the custom code to do the deduplication.
Step by Steps information in below thread for your reference to create the parameters and the custom code:
