Question

How do I exclude one value from a grouping sum, based on a value of another field?

ie I open Report=> Report Properties=>Code and insert my Custom Code, but how would I change the below code to exclude a numeric value of another field for the below case?

Public Function ChangeWord(ByVal s As String) As String    Dim strBuilder As New System.Text.StringBuilder(s)    If s.Contains('Others') Then       strBuilder.Replace('Others', 'Other NOT INCL')       Return strBuilder.ToString()       Else : Return s    End If End Function

I’m assuming you want to exclude a numeric value from a sum where the string value of a cell on the same row includes ‘Others’, and that the function you’ve supplied is used as the grouping criteria for a table in the report. Apologies if this isn’t correct.

It’s not going to be possible to do this without using a second piece of logic, either a function or an Iif condition. I don’t have SSRS available to test this at the moment, but (assuming your value column is an integer, the code will look something like:

Public Function ExcludeOthers(rowDesc As String, rowVal as integer)     if ChangeWord(rowDesc) = 'Other NOT INCL'         Return 0     else         Return rowVal     end if End Function 

Then, in the cell where you want the conditional sum to appear:

=Sum(ExcludeOthers(Fields!desc.Value,Fields!val.Value)) 

Alternatively, you could do this without the function by using Iif in the cell where the conditional sum will appear:

=Sum(Iif(ChangeWord(Fields!desc.Value) = 'Other NOT INCL',0,Fields!desc.Value)) 

Depending on the nature of your source data, you could also do this by adding calculated columns to the report’s source query.

I would favour the second or third option – custom code seems like overkill for this purpose.
