There is again small tips. Let me share you again scenario. Suppose you have to show customer Sale With customer group level. And group footer want to sum of Sales of that group. Now requirement is that customer with certain sub classification will skip in group sum. For example those customer who are on hold or blocked will not shown in report group sum, but shown in report detail
I was developing RDP based reports. So I add a int field in table. So I can mark specific record need to skip at group level sum.
I update the following SSRS expression to skip certain records at group level.
=Sum(iif(Fields!Flag.Value= 0, Cdbl(Fields!Value.Value), 0.0),”Group Name”)
