Sum Distinct <Field>

[#1]

Hello everyone,

I'm trying to sum some values from a field based on another one. I would like to use something like Sum(TOTAL <Invoice Number> Sales) but, instead to use TOTAL I need to use Distinct, due to I have many re-invoices numbers belonging to the same original invoice, and of course, I need to sum just one time each.

Thanks in advance!!!

Hi,

I think you have a problem in the original data. Try to understand why you have duplicate value for a unique invoice.

But you can try this :

sum( Aggr( Max( Sales ) , Invoice Number)) )

This function retain one value for each invoice.
