Enable Hybrid Object Sharing Rules
You can configure whether or not users can create hybrid object sharing rules for access groups.
A hybrid rule is a rule that includes a predefined rule condition with one or more custom rule conditions. Combining custom conditions with a selected predefined condition in a hybrid rule lets you refine the access that's provided by the predefined condition.
To enable hybrid rules, change the value of the profile option System and Custom Rule Conditions Combination Supported (ORA_MOW_SUPPORT_SEEDED_CONDITION) using these steps.
