问题
I would like to be able to get the percentage of each row with relation of the whole total. Here is my formula:
=COUNTDISTINCT(Fields!ID.Value, "NameOfRowGrouping") / COUNTDISTINCT(Fields!ID.Value, "TopLevelGroupName")
The percentage it comes out is the percentage between row total and total of each group:
Group Qty %
---------------------
Group 1
MemberA 3 40%
MemberB 4 60%
Total 7
Group 2
MemberC 2 50%
MemberD 2 50%
Total 4
Grand Total 11
I need to know the percentage with relation of the total for all groupings, like so:
Group Qty %
---------------------
Group 1
MemberA 3 30%
MemberB 4 40%
Total 7
Group 2
MemberC 2 15%
MemberD 2 15%
Total 4
Grand Total 11 100%

It sounds like what you want to do is calculate based on the dataset, not the table grouping:
=CountDistinct(Fields!ID.Value)/CountDistinct(Fields!ID.Value, "MyDatasetName")
