running sum

[chavez_sea]

Dear all,
I need some help with a query or if I need to run a report, to show the running sum of a field.

I would be grateful for some help.



Thanks

It's easiest on a report, using the Running Sum property of a textbox. It can be done in a query, but involves either DSum() or a subquery, either of which can really hamper performance with large data sets.
