To enforce that only Container__c records with a status of "Decommissioned" can be deleted, we need to prevent deletion of records unless they meet this criteria.

Possible Approaches:

Option A: Apex Trigger

Correct.

Explanation:

An Apex before delete trigger can be written to check the Status__c field of each record being deleted.

If the status is not "Decommissioned," the trigger can add an error to prevent deletion.

trigger PreventContainerDeletion on Container__c (before delete) {

for (Container__c container : Trigger.old) {

if (container.Status__c != 'Decommissioned') {

container.addError('Only decommissioned containers can be deleted.');

}

}

}

Steps:

Go to the master-detail field on OrderItem.
