The different entities in a model reference each other, so populating the input data in the correct order is important. This list show the correct order and dependencies. Entities with a higher indentation depend on entities with less indentation.
Start populating the entities at the top of the list and work your way down.
- Customer (references itself)
- SetupMatrix
- Skill
- Calendar
- Calendar buckets (references calendar)
- Location (references calendar and itself)
- Resource (references setup matrix, calendar, location and itself)
- Operation (references location)
- Resource skills (references skill and resource)
- Load (references resource, skill and operation)
- Sub Operation (references operation)
- OperationPlan (references operation)

Note that it is pretty straightforward to extend the data model to match your own domain model. During an implementation additional data types can be added that map more accurately to your business and/or data sources.
