How to give a permissions of business units in Salesforce marketing cloud?

Hi Rajan,

In the Admin Tab:

1. Click on the “Admin” Tab Click on “Business Units”
2. Search for your Business Unit by typing parts of the name in the “Search”
3. Press Search
4. Choose your Business Unit
5. Click Define Subscriber filter

A prerequisite to this will be to create a Subscriber Profile Attribute from Subscribers > Profile Management.

You will need to set the Subscriber with the profile attribute in order to define which business unit / Subscriber Filter they shall apply to.

Hope this will help you ...
