What should be recommended to ensure an email address is entered when selected to email a receipt?

To ensure that an email address is entered when the option to email a receipt is selected, implementing a Set Errors element is a suitable recommendation. This approach allows you to control the flow of the process by checking whether the email address field is empty. If it is not filled out, the Set Errors element can trigger an error message, effectively informing the user that they need to provide an email address before proceeding.

Using this method helps maintain a smooth user experience by providing immediate feedback and preventing the completion of the process until the required information is supplied. By directly linking the error handling to the specific condition of needing an email address, you ensure that necessary information is collected as part of the workflow.

The other options, while relevant in different contexts, do not directly address ensuring an email address is entered during this specific process. For example, retrieving the email address with a DataRaptor wouldn’t enforce its entry but merely obtain existing data. A Validation Rule could enforce data integrity at the object level, but it wouldn’t integrate directly when emailing a receipt in this particular process context. Similarly, a Conditional View may alter the presentation of the screen but does not enforce data entry in a required field. Therefore, utilizing a Set Errors element is the most effective solution in this
