Share Business Units

To set business unit access using any sharing model other than public read/write:

Note Make the Distributed Marketing Business Units object public read/write to allow all distributed marketing users to access any journeys from any business unit.

1. In Salesforce, navigate to Setup.
2. Under Security, select Sharing Settings.
3. Under Organization-Wide Defaults, select Edit.
4. For Marketing Cloud Engagement Business Unit, change Default Internal Access to Private.
5. Select Save.
6. Determine and implement a sharing model using Sharing Rules.
   1. Use manual sharing to give business unit access to specific individuals or groups.
   2. Use role hierarchy sharing to give users access to business units based on their Salesforce role.
   3. Use criteria or owner-based sharing rules to give users access to business units based on fields on the business unit; a user's role, group, or subordinate structure; or both.
   4. Use Apex managed sharing rules to programmatically create sharing rules that grant access to business units for both users and groups.
