# Installation and Licence

## Installation

The app ships as an extension for Microsoft Dynamics 365 Business Central and is installed from the marketplace.

{% stepper %}
{% step %}

#### Find the extension

In Business Central open **Extension Management** and choose **Marketplace**. Search for **DATANORM Item Import**.
{% endstep %}

{% step %}

#### Install

Installation creates the tables, pages and permission sets. No tenant restart is required.
{% endstep %}

{% step %}

#### Assign permissions

Give your users one of the three permission sets, see [User Roles & Permissions](/datanorm-item-import/datanorm_en_us/getting-started/user-roles-and-permissions.md).
{% endstep %}

{% step %}

#### Configure

Continue with the [Setup Wizard](/datanorm-item-import/datanorm_en_us/getting-started/setup-wizard.md).
{% endstep %}
{% endstepper %}

{% hint style="info" %}
Always trial a first import in a sandbox environment. An article import changes master data, and a full catalogue can create several thousand items.
{% endhint %}

## Licence

The app is obtained and licensed through **Microsoft AppSource**. The term follows your AppSource subscription and is managed through Microsoft. Nothing needs to be configured or entered inside the app.

### Trial and sandbox builds

If you receive the app directly from solutioo for evaluation instead of taking it from AppSource, that build carries a fixed expiry date. Its status is then shown in **DATANORM Setup**.

<table><thead><tr><th width="260">State</th><th>Behaviour</th></tr></thead><tbody><tr><td>Valid</td><td>All features are available. The status shows the expiry date.</td></tr><tr><td>Expiring within 14 days</td><td>A notice appears with the number of days remaining.</td></tr><tr><td>Expired</td><td>Import and synchronisation stop with a message. Data already imported stays intact.</td></tr></tbody></table>

{% hint style="info" %}
This expiry date applies only to trial and sandbox builds handed over directly. An installation taken from AppSource does not carry it.
{% endhint %}

{% hint style="warning" %}
An expired trial blocks importing but deletes nothing. After moving to the AppSource version you carry on without any rework.
{% endhint %}

To extend a trial period, get in touch using the details under [Support Contacts](/datanorm-item-import/datanorm_en_us/operations-and-troubleshooting/support.md).

## 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://docs.solutioo.de/datanorm-item-import/datanorm_en_us/getting-started/installation-and-licence.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.
