# Region Properties Panel

## **What is a Data Region?**

A Data Region is an area of data captured within your report. It can cover any number of lines in a source report. This area is defined by specifying a pattern.

Setting up a data region is one of the first steps in extracting data from a report. Data regions are the backbones of Report Models – they direct Astera on where to extract data from.

To support the selection of data regions, Astera contains a set of Region Properties.

*Region End Type:* With the options available in the drop-down list, you can specify where you want to end your data region. The options in this dropdown menu are as follows:

* *Line Count*: Ends your region after a specified number of lines. It allows the user to vary the line count according to the requirement of the data region.
* *Blank Line*: Ends your region where a blank line occurs.
* *Last Field Ends*: Ends your region at the last data field within your data region.
* *Another Region Starts (100 Rows Max)*: Ends your first data region where the next data region begins. This is used for variable-length data regions.
* *Till Regular Expression*: Ends your region when the specified regular expression occurs.
* *Till Specific Text*: Ends your region when the specific text string occurs.

{% hint style="info" %}
**Note:** The *Line Count* option appears dynamically, depending on which option is selected from the dropdown menu of *Region End Type*.
{% endhint %}

*Overlapping Container:* Used when there are multiple data regions with overlapping lines.

*Container Region:* Used when a data region contains a sub-region within its boundaries.

This is how you can define and modify Region Properties in a Report Model.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://documentation.astera.com/astera-data-stack-v9/report-model/report-model-interface/region-properties-panel.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
