SSRS 2008 - How to SUM a FIRST() in a MATRIX?


Why is something that should be so easy be so difficult?

Is there a way to SUM a FIRST() in a MATRIX cell? I have a column of data that is displaying the First(Fields!Annual_Spend.Value, "DataSet1"). I simply need to SUM this column of FIRST's...what's the trick..?????

Any ideas?

As far as I know, =sum(first()) is same as SUM(DISTINCT) in sql server.

So, why not do this in sql query so you won't have to worry about it in report designer?

can you explain further like which column is used for matrix row group and column group? and how you want the data to be computed? (sample data from dataset also)

bmendoza - I can explain more, but it's a little complicated. I think if I can simply understand for certain that I will NEVER be able to SUM the FIRST() function, then that will tell me at this point, what I need to know and how to proceed.

I use quite a few reporting products out on the market. (ie. Crystal Reports, Business Objects XI, Microstrategy, etc...) Most of these products are able to handle these types of summaries, but SSRS doesn't seem to have an easy solution...?

Is there perhaps a VARIABLE type of function, that I don't know about that I can store a value of a GROUP and summarize it.., then display the SUM at certain intervals of the report,or certain Group Footers..???

Also, needs to be in a Matrix due to the columns need to be dynamic based on a change in Supplier Name.
have you tried combination of list and matrix? (matrix inside a list maybe)

Had to use First() function and group footer to display the correct amount in the cell, then created another SQL query to provide the SUMs.

Exported to Excel to manually test all summaries in Excel.....

Worked for me,...not the most efficient what to handle though, but all that SSRS could provide....
