SSRS 2005 Roll Up Average in Report

Posted on 2012-04-02

I have a report that currently lists data like:

DEPT         %                         <--Row
-------------------------
Supply          18.00 %             <--Group
Marketing    12.01%
Sales              5.03%
...
--------------------------

I need to be able to provide a rollup of the percentages. So in this example it would report back 11.68%

The issue is that the '%' column expression is
=round(sum(iif(Fields!MTR.Value = "False", 1, 0))/Count(Fields!MTR.Value),2)

So what I am 'trying' to do is something like
=AVG(round(sum(iif(Fields!MTR.Value = "False", 1, 0))/Count(Fields!MTR.Value),2))

but I get an error about
'The value expression for the textbox 'textbox71' contains an aggregate function (or RunningValue or RowNumber functions) in the argument to another aggregate function (or RunningValue). Aggregate functions cannot be nested inside other aggreagte functions.

Ideas for a work-around?

No, but thanks.

I found a work around by creating additonal subreports that summarized the data and put them on the overall report. Not the way I wanted but I was against a time crunch.
