Accessing Approval Management Engine (AME) is not possible as we access other responsibility / functions in Oracle Applications like Order Management / Application Developer etc.
AME is controlled by RBAC (Role Based Access Control). So in this case even you assign responsibility to the user but if user don't have the appropriate roles then you will not be able to access Approval Management functions.
There are two seeded responsibility for AME :-
- Approvals Management Administrator
- Approvals Management Business Analyst
Let's assign the responsibility directly to user and see what happens.
