 issues
+ - [ ] baseline needs to populate all columns in sequential order like the scale route
  - [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?
