Go to Navigation pane > Modules > System administration > Users > Users.
In the list, find and select the desired record.
On the Action pane, click User options.

Box 2: Dynamics 365 Field Service
Supply Chain Management enables synchronization of business processes between Dynamics 365 Supply Chain Management and Dynamics 365 Field Service. The integration scenarios are configured by using extensible Data integrator templates and Common Data Service to enable the synchronization of business processes. Standard templates can be used to create custom integration projects, where additional standard and custom fields and entities can be mapped to adjust the integration and meet specific business needs.
