There is a standard site map for all Dynamics 365 instances, but chances are the default site map does not scream ease of navigation for your organization. It is important that Users can easily find the entities they need without hunting column by column, and more importantly they see what they need to see, and ONLY what they need to see.
Dynamics 365 provides the ability to modify the standard site map without coding, allowing everyday users to easily modify the layout, making it a better fit for your business. You will need either the System Administrator or System Customizer role to perform the following actions.
To customize the site map, simply go to Settings > Customizations > Customize the System.
You will find multiple site maps under Client Extensions, there is typically one which contains all apps, and then others which are each tied to a specific app.
In this case, we are using the default one which is labeled “Site Map”.
