In SSRS, aggregate measure based on dimension value

Question

I am writing an SSRS 2012 report whose data source is an SSAS cube. In one table of this report, I am using a very simple data set with one dimension (Category) and one measure (Sales). The dimension has 4 members, A B C D. For the purposes of this
report table, I want to show the sum of sales for A, the sum of sales for C, and the sum of sales for B and D combined. I then want to show each of these 3 values as a percent of the total (sum of A B C D).
The data set looks like this:
CATEGORY   SALES
A                10000
B                14000
C                 8000
D                 8000
The resulting report table should look like this:
CATEGORY SALES % OF TOTAL
A                10,000      25.0
B+D            22,000      55.0
C                 8,000       20.0
TOTAL         40,000

Hi ,
As you mentioned you need such aggregation in SSRS and you are using SSAS datasource.
so you can achieve this using MDX Query.
I have done this in my environment . I took below for achieving this
Dimension : Category
Relationship : There should be Facttable relationship with Dimension table Category.
Measure : Unit Price (in your case sale)
Please find below solution using MDX Query.
Please share if you have any doubt.
Thanks
