ABSTRACT:
The present invention discloses a method, computer program product and system for adjusting roles in a computer system (100) that launch application services (301-307) by a first user who is assigned to at least one role. A first role (110) calls a second role (150) by reference (111). Both roles comprise representations of applications services (101, 102, 103) and (104, 105). When representations in the second role are modified, for example, application services are added (106, 107), a delta list (112) for the first reference is automatically created to conditionally prevent the first role (110) from referencing to at least some of the modified representations of the second role (150). This is achieved by using a rule database (118) containing rules about application services that are mutually exclusive and checking for conflicts between the representations of the first role and modified, second role. A second user, e.g. a system administrator, can accept or reject automatically created delta entries (114) in the delta list (112).
