It is possible to authorize a user group for a trading partner only. This will not automatically authorize the user to see MRP areas or plants associated with the trading partner. 

To authorize a trading partner for a user group: 

1. Using the Advanced menu, click System Admin > User Management > User Partner Authorization. 
2. Select the User Group from the Select User drop down list. 
3. All existing authorizations are currently visible in the Existing Authorizations table on the left. 
4. Search for the trading partner to authorize from the Potential Authorization table on the right.  

• Search by trading partner name or by trading partner code. 

5. Select each trading partner to authorize. 

• Once authorized, the trading partner will be moved from the Potential Authorizations to the Existing Authorizations table. 

6. Next, we need to replicate the user group that was just updated. 

• See Replicating a User Group.
