I have SSRS 2008 tablix region where the columns are State,Category,January, February, March,...,December, YTD. I have pivoted the table in sql server and have all the sums (total sales, etc) and percentages (product category% of total, etc)for each month (columns). I need help to calculate the YTD when the column is %.
example:
State Category January February March......YTD
MN A 200 200 0...... 400
MN B 21 12............ 0........ 33
MN A% 12.5 12.5 0........ ??
For A,B above, the YTD is simply adding the report items January+February+March+....
For A% above(??), since this a percent column, my YTD should be the average of the non-null columns...in this case (12.5+12.5)/2=12.5 but I am unable to find out the count of the non-null columns for each category (January, February, etc)...I have tried ave,count, sum, etc but i am not getting the correct value. If I can figure out the denomintor(which will be the count of the non-null columns in January, February,...,December), the problem will be solved.
