Hi there,

I'd like to sum only the first row of each category of the grouping. This is because there are duplicates in the database i.e.


Contractor      Amt    InvoiceNo     AwaitingValidation
ABCfixers       200      1              4    
ABCfixers       100      2              4 
ABCfixers       150      3              4
123Diggers      50       1a             12
123Diggers      100      2b             12
123Diggers      455      3b             12 
123Diggers      120      4b             12

There's only 4 invoices awaiting validation for ABCfixers and 12 for 123Diggers.

In SSRS, If I sum this for the Contractor group I'll get 16 for ABCfixers and 48 for 123Diggers.

I want to know if I can take the first row of each 'Contractor' and sum that only within ssrs

Is there a way to do this?

Many thanks

It will be easier to help if you can give wanted output in relation to sample data...

No, you're never too old to Yak'n'Roll if you're too young to die.

Thanks for replying.

At first I was doing a join with the contractor tables and the table with validation dates, via contractorID. This is what's giving me the dupliates. I was going to sort this out via SSRS

Instead, I've done Union all to pull the data I need to show in the grouping and filtered out these rows in SSRS

I appreciate the request for output data but the work around will do for now.

Cheers

add a rownumber for group and put rowno=1 in condition inside sum like
=Sum(IIF (Fields!RowNumber.value=1,Fields!Amt.value ,0))
