 issues
+ - [ ] what if you create a func table but some of the values are null? (orders without quotes)
+ - [x] what if you want certain things like invoice numbers included in the baseline, is a func table necesary? no, just leave fkey null and no table will be setup
  - [ ] baseline needs to populate all columns in sequential order like the scale route
+ - [ ] what if there is more than one table in fc.target_meta
  - [x] validate the ability to join to associated date tables, for example order season that needs incremented
  - [ ] there is not currently any initial grouping to limit excess data from all the document# scenarios
  - [ ] how to handle a target value adjustment, which currency is it in?
