Update 30 September 2021: while this article is worth reading for background information, I now recommend using the approach utilized here: Virtual List Reporting, part 4
Last year I posted a couple articles on the topic of virtual list reporting (part 1 and part 2), a.k.a. VLR. Today we’re going to look at some additional things you can do with VLR, and to avoid a lot of repetition, this article will assume the reader is familiar with the material covered in part 1, wherein benefits are extolled and fundamentals explained.

Did you notice in parts 1 and 2 that we were limited to producing a single report at a time? Yes, we could sequentially output them and concatenate them into a PDF, but we couldn’t display multiple reports on-screen simultaneously, nor could we interact with them in browse mode.
This time around we’re going to look at a method to produce multiple independent reports concurrently, each in its own window, based on a single virtual list table. This will entail generating a large number of dynamically instantiated $$vars[withReps], so we will also explore a way to automatically clear them out (without the overhead of having to keep track of them during instantiation).
Disclaimer/Warning: before running multiple Customer reports, open your Data Viewer and activate the Watch tab. You don’t want to display the Current tab with 5K or more variables in memory, unless you’ve got a lot of… time… on… your… hands.
