Working with Bryan. We looked at some code and made a few tweaks to some of his reports and pages. We then switched gears over to sub inventory with location filters. Once you add locations into the mix, it complicates things. It goes from a one-to-one relation to a one-to-many relation. That then requires grouping, dynamic filters, and dealing with scale. Lots of talk about dynamics, deeper groupings, and how to sub filter grouped results. We also talked about getting good data and small control set to make sure we are getting what we want (known data in order to get known output).
