# Configure Document Splitter skill parameters

> Configure Document Splitter skill parameters to connect data catalogs, set text values, or toggle Boolean flags without retraining.

Skill parameters let you adjust a Document Splitter skill's behavior — connect data catalogs, supply text values for regular expressions, or toggle Boolean flags — **without retraining and republishing the skill**. You can use parameters in:

* [Classify By Company](/vantage/documentation/advanced-designer/activities/classify-by-company) activities, for accessing data catalogs, writing regular expressions, and supplying keywords to improve search accuracy.
* [Extraction Rules](/vantage/documentation/advanced-designer/activities/extraction-rules/extraction-rules) activities, for the same data catalog, regular expression, and other in-activity options.

Parameters can be created and edited in either Advanced Designer or Vantage. Their values can also be overridden per transaction via the Vantage API. For broader background, see [Skill parameters](/vantage/documentation/skill-designer/skill-parameters/skill-parameters).

## Use cases

The examples below use built-in Document skills, but the mechanics apply equally to Document Splitter skills.

### Process invoices from different customers using each customer's data catalog

To run the same built-in [Invoice skill](/vantage/documentation/skill-catalog/built-in-skills/invoice-skills/invoice) against multiple customers, route the right data catalog into each transaction with a parameter. Built-in skills like Invoice ship with **default parameters** that point at the data catalogs they use — pass a different catalog per transaction via the Vantage API.

### Restrict country and expense-type detection in the Receipt skill

To process retail receipts from one country only, use the [Receipt skill](/vantage/documentation/skill-catalog/built-in-skills/receipt-skills/receipt) default parameters. For example, set country to `DE` and expense type to `GeneralRetail` to process German receipts only — the **Country** and **Expense Type** fields are pinned, and processing runs faster.

## Skill parameter types

| Type             | Description                                                                      |
| :--------------- | :------------------------------------------------------------------------------- |
| **Data Catalog** | A connection string to a data catalog on the Vantage server you're connected to. |
| **Text**         | A string value (raw or a regular expression).                                    |
| **Boolean**      | `Yes` or `No`.                                                                   |

## Edit or create a parameter

<Steps>
  <Step title="Open skill settings">
    Click the settings button next to the skill's name.
  </Step>

  <Step title="Open the Parameters tab">
    Switch to the **Parameters** tab.
  </Step>

  <Step title="Edit or add a parameter">
    To edit a parameter, select it and change its value. To add a new parameter, click **Add Parameter** and:

    * Choose a parameter type.
    * Provide a name (or accept the default). Names must be 256 characters or fewer.
    * Set a value:
      * **Data Catalog** — pick a data catalog from the drop-down.
      * **Text** — enter a string or a regular expression.
      * **Boolean** — choose **Yes** or **No**.
    * Optionally add a description.
  </Step>

  <Step title="Save">
    Click **Save**. The parameter is now usable in any compatible activity.
  </Step>
