What will happen if a Salesforce (SF) field referenced in an Enterprise Application is deleted?

When a Salesforce field that is referenced in an Enterprise Application is deleted, the synchronization process will fail for that object. This occurs because the application relies on the specific field to map data correctly between Salesforce and the external system. Without the field, the application cannot correctly reference the data it needs to synchronize.

When a field is no longer available, the necessary connections and data mappings become invalid, leading to sync errors. The synchronization process depends on the existing schema, and removing a field disrupts that structure, resulting in failure to synchronize data for that specific object.

Other options suggest that the deletion might not impact synchronization, which does not align with how dependencies in data integrations typically work. If a field is an integral part of the object's data structure, its deletion will result in a failure of the sync process, hindering the ability to update or retrieve data properly until the issue is resolved or the field is restored.
