Final answer:
The recommended solution is to use validation rules in Salesforce to enforce the requirement that the associated account's billing state field has a value and cannot be changed after the opportunity has been created.
Step-by-step explanation:
The recommended solution to configure the automated behavior in this case is to use validation rules in Salesforce. A validation rule ensures that certain conditions are met before a record can be saved. In this scenario, you can create a validation rule to check if the associated account's billing state field has a value when an opportunity is created and make it read-only after that.
Here's an example of how you can set up the validation rule:
- Create a new validation rule on the Opportunity object.
- Set the rule criteria to 'ISNEW() && ISBLANK(Account.BillingState)'
- Add an error message to inform users that the billing state field of the associated account cannot be blank.
- Optionally, make the billing state field read-only using field-level security settings.
By implementing this validation rule, you can enforce the requirement that the associated account's billing state field must have a value and cannot be changed after the opportunity has been created.
