# How to set up permissions

### What are permissions & permission groups <a href="#permissions-and-permission-groups" id="permissions-and-permission-groups"></a>

A range of permissions exist by default in Struct PIM, and they are divided into permission groups. A permission defines an access right described by its name ranging from access to viewing products to configuring data models.

In configurations of global lists, catalogues and product structures, new permissions can be defined to limit users' access to a specific part of the data models.
