Examples of Creating Custom Entity Fields 

Create an Entity Field With a One to Many Relation 

As the first example, we are adding a new field called Referral to the Customer entity, so we could track the contacts recommended by particular customers. This should be a one to many relation because one customer can give details of more than one contact.

To create such field:

  1. Navigate to System > Entities > Entity Management in the main menu.

  2. Using filters, find the Customer entity, and click on it once to open its page.

    Navigating to the customer entity using filters

  3. On the page of the Customer entity, click Create Field.

    View the create field button on the customer entity page

  4. For Storage Type, select Table Column.

Create an Entity Field With a Many to One Relation 

As the second example, we are creating a Business Unit field for the opportunity entity, so that it is possible to relate an opportunity to one of the existing business units. The relation should be many to one because one business unit can be related to many opportunities.

To create such field for the opportunity entity:

  1. Navigate to System > Entities > Entity Management in the main menu.

  2. Using filters, find the Opportunity entity, and click on it once to open its page.
