## How to Copy Model Master into Item Description - 3 When Creating a New Item?
In this tutorial, we’ll explore the configuration option **“Copy Model Master in Item Description 3”** while creating an item in Logic ERP.

***
### Implement with Feature Disabled
* Keep the option **disabled**.
* Firstly, Go to **Column Locks** and enable both:
* **Item Description 3**
* **Part Model**
* Now, create a **new item**.
* In **Linked Parts and Models**, enter the **Model Master** and save the item.
* Reopen the item to review details.
Since the option was disabled, the **Model Master is not copied** into **Item Description 3**.
***
### Implement with Feature Enabled
* Go back to **Configuration** and **enable** the option.
* Create a new item again and save it.
* Reopen the item to review the details.
This time, the **Model Master is automatically copied** into **Item Description 3**.

This feature ensures **consistency and automation** when managing item details.

## 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://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/setups/setup-items/setup-items-multiple-pack-sizes/configuration-multiple-packs-sizes/configuration-options-1/copy-model-master-in-item-description-3.md?ask=&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.
