# Pre Calculation

- [Calculation](https://brenkel-solutions-eg.gitbook.io/dp-calculation-eng/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/dp-calculation-eng/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/dp-calculation-eng/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/dp-calculation-eng/pre-calculation/schemas.md): The precalculation schemes are for the evaluation of the individual processes.
- [Templates](https://brenkel-solutions-eg.gitbook.io/dp-calculation-eng/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/dp-calculation-eng/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/dp-calculation-eng/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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://brenkel-solutions-eg.gitbook.io/dp-calculation-eng/pre-calculation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
