如何在SSRS中汇总百分比

Question

I want to add a total field to a table with percentages.

The AVG() Function within SSRS doesn't work for me because of the following reasons. ( The measures are in percentages)

 _______________________________
 |Group 1| Measure 1| Total 1   |
 |_______|__________|___________|
 |Group 2| Measure 2|           |
 |       | Measure 3|Total 2    |
 |_______|__________|___________|
 |Total  |__________|Grand Total|

If Measure 1 is 100 %
And Measure 2 is 0%
And measure 3 is 100%

Total 1 will be 100%
Total 2 will be 50 %
Grand Total will be 75% (100 +50 /2)

While it should be 66% (100 + 100 + 0 /3)

The percentages are precalculated.

Answer 1

Instead of calculating the average of the Totals , calculate the grand total of all Measures . So you should be able to use the AVG() function on all the measures of your datasource.

=AVG(Fields!Measure.Value)

This will basically calculate the total sum of all measure values and divide it by the amount of records that are in your datasource.
