Your first calculated attribute script

A calculated attribute evaluates its script when the attribute's value is needed. The current entity is available as subject, and the script's returned value becomes the attribute value.

1. Create or edit a calculated attribute for the Crm.Sales.Customers repository.
2. Configure it to return a string and select JavaScript as its script language.
3. Set its script text to:

return subject.Active ? "Active" : "Inactive";

4. Save the attribute and read its value for a customer.

Calculated-attribute JavaScript is a function body, so a top-level return is valid. It does not use a managed-script parameter schema or return envelope. Keep calculations efficient: this value may be requested repeatedly in forms, lists, and reports. See configuration and calculated-attribute examples.
