The Automatic Configuration creates the foreign key on the Clause Library's Master Object without field-level security. It is not visible to any profile. Therefore, the "Select Clause Bundle" user interface will give the "Clause Bundle selection is not supported on this object" error when trying to populate Managed Clauses on the master object. For the Select Contract Template process to work, the field must be visible to the correct profiles.
- Navigate to Setup > Create > Objects > Your Master Object > Managed Clause .
- In the Custom Fields and Relationships box, Click Contract.
- Click Set Field-Level Security.
- Select Visible for all of the necessary Profiles.
- Click Save.
