After my last video and blog post on 5 ways to sort Jet Reports, Mario from Jet Reports Spain asked for a tutorial on the "sort on sum" technique. So I made one!
Full disclosure. This is not an easy technique! It requires a little knowledge about using double quotes, ", in Excel strings, as well as adding calculated fields inside of Jet replicators using NF functions. It may seem a little confusing, but if you give me 40 minutes of your attention, hopefully it'll all make sense.
Fair Warning: Only use calculated fields in your report if you absolutely need it (because it reduces report performance).
Like what you saw?
Have reports that require construction?
Give us a holler.
