# Schemas

{% hint style="info" %}
The row layout and column layout is similar to the logic in the [schema templates](/dp-calculation-eng/post-calculation/schema-templates.md).
{% endhint %}

{% hint style="info" %}
If you change anything in the scheme, you need to update the scheme. After that, the corresponding entries will be recalculated.
{% endhint %}

## Manual creation

If you do not have a post calculation schema template stored, you can also enter the schemas manually.

## Calculation Entries and Calculation Values

### Calculation Entries

When updating the scheme, so-called calculation entries are created. These form the basis for further evaluation.

For item, machine center, work center the individual lines of the calculation are transferred. At this point, the filters of the schema are also taken into account. If, for example, only a certain item category is evaluated, only the corresponding items appear in the items for this line of the schema. The individual surcharges are also calculated here, if they are required.

You can open the entries via the lookup by clicking on the number of a line with the appropriate summation type.

### Calculation Value

The calculation values are the “results” of the calculation. For each combination of row (line) and column, the associated value is logged there and displayed in the page.

## 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/post-calculation/schemas.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.
