Understanding Entities

Add custom entities and modify business entities to match your evolving business needs. Make these changes directly from the Microsoft Dynamics CRM Online user interface. No programming is required.

To customize entities, you must have the System Administrator or System Customizer security role, or have equivalent privileges. More information: Permissions required for customization

Each entity has a number of fields. There are two types of fields:

  • Business fields. These are any standard Microsoft Dynamics CRM Online field that can be customized or added to a solution. When part of a solution, business fields might be further customizable, depending on the restrictions placed on them when creating the solution.
  • Custom fields. These are created in the customization area and can be included in a solution. Custom fields might be customizable further, depending on restrictions placed on them when creating the solution.
