I've come across the well known problem of needing to nest aggregates in a report which has a table with groupings. I have come up against a bit of a problem with the suggested workaround posted in severla threads of using custom code and variables as a way round this.
Basically I have several groupings in my report, the inner most of which has a field which needs to return the MAX value of the rows contained within it. Then depending on what this value is i need a count of these values that match a particular criteria eg if it ends in a "T" count it if it doesn't then don't.
I have a businees area group surrounding that inner grouping and i need to sum to the rows that match that particular criteria, but i can't have a sum of the values because they are calculated using the MAX aggreagte.
The partial way round it i have found is to use some custom code and create a variable that i can increment each time one of the rows matches the criteria i want
Public Shared sum_monday As Integer = 0
Public Shared Function SumMon(ByVal Value As Integer)
sum_monday = sum_monday + Value
End Function
i use the code below to increment the variable
and in the group footer i use the code below to display the total
the problem i have is that i can't work out how to reset the count for each grouping because at the minute its effectively a running total. I need to have a sum of the particular group rather than a running sum including all the previous groupings.
Apologies if some of the above isn't clear , i'm a bit useless at writing clear explanations
Any help much appreciated.
