# Considerations for Data Stream Field Disablement

There are few restrictions to consider when planning to disable a data stream field.

### Required Editions

## Common Considerations

You can't disable these types of data stream fields.

- Fields used as part of the Primary Key, Event Date Time, Organization Unit Identifier or Record Modified fields.
- System-generated fields such as Data Source, Data Source Object, cdp\_sys\_SourceVersion, and Internal Organization.
- Fields used as source fields in any other formula field.
- Fields of a data stream that is deployed from a Package.
- Fields of data stream ingesting data from Marketing Cloud Engagement Bundle and Mobile SDK streams.

## Considerations for Disabling a Field in CRM

- To delete a field from your connected CRM, first disable that field from Data 360 to avoid ingestion errors in data streams.
- After you disable a field, you can delete the field through the connected Salesforce CRM Object Manager admin tool. Then remove the field from the Data 360 permission set in that connected Salesforce CRM.
