# Pre Calculation

- [Calculation](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/pre-calculation/calculation.md): The calculation is the heart of the complete module. Its where boms and routings will be exploded, aswell as costs for later evalatution calculated.
- [Processes](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/pre-calculation/processes.md): A precalculation process combines several calculations. The aim is to be able to calculate and compare several lot sizes for one item.
- [Schema Templates](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/pre-calculation/schema-templates.md): With the help of the schema templates you can predefine schemas and apply or store them to the different schemas, processes and calculation templates.
- [Schemas](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/pre-calculation/schemas.md): The precalculation schemes are for the evaluation of the individual processes.
- [Templates](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/pre-calculation/templates.md): With the help of templates, you can always create new precalculation processes for specific items and have them calculated.
- [Fields](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/pre-calculation/fields.md): To create as much transparency as possible, all relevant fields are explained and described.
- [Quantities / Cost logic](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/pre-calculation/quantities-cost-logic.md): In the following, the logic for the quantities, prices and costs is explained for the fields of the pre calculation.
