# Planning Calibration

- [Functions](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/planning-calibration/planning-calibration/functions.md)
- [Lines](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/planning-calibration/planning-calibration/lines.md)
- [Inventory Costs](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/planning-calibration/planning-calibration/inventory-costs.md): The inventory costs are calculated for each period of the planning calibration. They are the basis for calculating the reorder quantities.
- [Period lines](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/planning-calibration/planning-calibration/period-lines.md): The period lines are separate planning calibrations for each individual usage period of the planning calibration.
- [Usage Period Templates](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/planning-calibration/planning-calibration/usage-period-templates.md): The intention of usage period templates is, that the user does not have to enter all usage periods for each planning calibration, but instead can use templates.
