=iif(Fields!Posting_Date.Value>="10/01/2011" AND Fields!Posting_Date.Value <="10/31/2011" AND Fields!Source_Code.Value="ACTJNL",Fields!Amount.Value,0.00)
I can't sum this calculated field in a group. Does this have to do with nesting aggregates? Is there a solution in SSRS2008? I can get around this issue by creating the formula in the datasource. However, I'd like to know how others have solved similar issues.
Thanks,
David
