Usage considerations

Where to use this function

The a!customFieldLogicalExpression() function can only be used to create a custom record field that evaluates in real time. This means you can reference related record fields, constants, and other supported functions in your calculations.

To create a custom record field that evaluates in real-time:

  1. In your record type, go to Data Model.
  2. Click NEW CUSTOM RECORD FIELD.
  3. From SELECT A TEMPLATE, choose Write Your Own Expression.
  4. Choose Real-time evaluation.
  5. Click NEXT.
  6. Enter an expression using any Custom Field function.

    Custom record fields that evaluate in real-time must use at least one Custom Field function.

  7. Click NEXT.
  8. Enter a Name for your custom record field.
  9. Click CREATE.
  10. Click SAVE CHANGES. The new custom record field appears in your list of fields.
