# Module Introduction

## About Validation

The Validation module enables advanced property validation based on various triggers, such as object creation, changes to workflow states, and more. It validates properties not only on the main object but also on referenced objects, even when these properties are not directly visible. The module searches and checks if the property exists or not. By setting multiple validation rules for a single trigger source, you can ensure that all necessary conditions are met before the object is approved or saved.

## Accessing Validation

After you have successfully installed the application, you can start adding calculation rules.

1. Open M-Files Admin.
2. In the left-side tree view, expand the desired connection to M-Files Server.
3. In the left-side tree view, expand the Document Vaults node.
4. Still, in the left-side tree view, expand the vault where you installed the connector and select **Configurations**.
5. Expand **Other Applications.**
6. Expand **Extension Kit.**
7. Click on **Validation.**

## Initial configuration steps

To begin configuring a rule, you need to define four fundamental fields to establish the rule’s essentials. For detailed descriptions, please click on each field below:
