Multiple User Roles to same User

Hi ,

We have a business scenerio where in we need to provide different user roles to single business user in JDE E1 9.0 environment. Due to the complexity of business it is not feasible to create those many user roles with different permutaion and combination of roles. e.g. User1 is assign role Processing Manger , Purchase User both. We can not create a seperate role combiniing processing manager and purchase user access as there are many permutation and combination of these and maintenance will not be practicle.

Problem here is if we access multiple roles to user then every time he logges in , he needs to select user role while entry and he can not access multiple areas in single sign on.
