# Functionality Management System Introduction

The Functionality Management System (FMS) allows Atlas Copco customers to use additional desired features, when they are needed, through a dynamic licensing scheme.

After receiving a purchase order, the customer’s account in Atlas Copco License Portal (ACLP) will automatically receive the purchased features within 24 hours and these features can be downloaded as a license file.

This capability file (included in the license agreement) is loaded in the Local License Server (LLS) where it is decoded and available for distribution.

A pool of features is created and may be used across a number of controllers. A desired feature item can be uploaded to the controller when needed, and be returned to the pool when it is not needed anymore.

In the Atlas Copco License Portal (ACLP) it is possible to manage an account with all features, entitle and return licenses to/from a license server.

The creation and management of a customer account in the ACLP is not covered in this documentation.
