Hello,
I am new to Report Builder and I am seeking assistance to write an expression that is a conditional sum.
I am attempting to sum the “Check/EFT Amount” values, if the “Check/EFT Number” is between the first and last “Check/EFT Number” values of the semantic model dataset. The first and last “Check/EFT number” values are dynamic value and will change based on the provided parameter date value. The Starting query below is the query from SAP business objects that I am attempting to replicate in Report Builder.
The Error I receive is “uses a First, Last or Previous aggregate in an outer aggregate. These aggregate functions cannot be specified as nested aggregates.”
For reference, I have attempted to use Min and Max, which avoids the error but the resulting values are different than First and Last. Therefore I do not receive the expected sum amount. I have also attempted a custom code solution with no success.
Starting Query (SAP):
=Sum([DISB Actg Line Check Amt])
Where ([DISB Hdr Check No] >= [Var - Begin Check Number ] And [DISB Hdr Check No] <= [Var - End Check Number])
My Report Builder Expression:
=Sum(IIf(Fields!Check_EFT_Number.Value >= First(Fields!Check_EFT_Number.Value) And Fields!Check_EFT_Number.Value <= Last(Fields!Check_EFT_Number.Value), Fields!Check_EFT_Amt.Value, 0))
cuold you pls provide some sample data and exepcted output?
