SSRS percentage of a total

Question

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, \"NameOfRowG         


        

Answer 1

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")
