Multi Org Security, Diagnostics Security and Application Appearence via Profiles

While using multi org application assigning profiles are critical at responsibility level;
MO: Operating Unit
MO: Default Operating Unit
HR:Business Group
HR: Security Profile
GL Ledger Name
GL: Data Access Set
MO: Security Profile (If MOAC is going to be used then a security profile should be created via HR and this profile should be set. If this is set then MO: Operating Unit is disregarded)

Normally Diagnostics on Forms require Apps password though in test or development environments this may cause problems. To make Diagnostics available for every user "Utilities:Diagnostics" profile can be set.

When an unexpected error occur in OAF screens, details of the error gives reason. To access to the details of error "FND: Diagnostics" profile should be set.

Changing the applications look and colour is possible. Especially differentiating test, dev and prod environments may prove very useful, to provide that "Java Color Scheme", "Java Look and Feel" profiles can be used.
