I have a simple matrix as such:

Rows: Return reasons
Columns: Week Start Date
Data cells:
Two text boxes in each column:
1) Sum of RMAs (works as desired)

2) In the second data text box, I want to have the percent of RMAs for that cell based on the column total. The only total I can get in my expression is the total for the whole grid - not the specific column.

I'm sure it's something simple (at least I hope!), so any help would be appreciated.

Thanks in advance.

Assuming the name of the column group is WeekStartDate, something like the following should work:

=iif(iif(isnothing(Sum(Fields!RMAs.Value,"WeekStartDate")),0,Sum(Fields!RMAs.Value)/Sum(Fields!RMAs.Value,"WeekStartDate"))=0,nothing,Sum(Fields!RMAs.Value)/Sum(Fields!RMAs.Value,"WeekStartDate"))

Note: the expression above is also eliminating divide by zero errors

Hope this helps!

Thanks! This works great! Make sure to go into your matrix properties to look up the column name...(in other words, it's the overall matrix column name, not the individual column name).

I think I have a similar question, in trying to get a column group's percentages. I want to calculate a matrix running total within columns groups, then use these values to get a percentage. I'm sure inscope is part of the solution but I can't seem to get the results I need.

Please review the attached example, as showing is easier to explain!

It's been sometime since your post, but this was the best solution I found today for this issue. Only thing is if you have a group subtotal the subtotal will also include the % that will always be 100%. I have to work out an expression to hide the % column on the subtotal.

I have a similar issue I think - and really struggle with the principle of scope being a part time developer! I have a matrix that shows the last 6 months as columns, call types as rows, and the number of calls by type. I have managed to calculate the percentage overall of calls by type, but want to do a comparison to show what the percentage is just for the current month as well as the 6month total. How do I select a specific column value to work with please?
