How Does the MOAC(Multi Org Access Control) Defaulting Rules Work in EBS R12

       How Does the R12 MOAC Defaulting Rules Work?

1. If the profile option “MO: Security Profile” is not set, then “MO:
   Operating Unit” value is used as the default Operating Unit even if “MO:
   Default Operating Unit” profile is set to a different value.

2. If the profile option “MO: Security Profile” is set and gives access to
   one Operating Unit, the default Operating Unit will return this value even if
   “MO: Default Operating Unit” is set to a different value.

3. If the profile option “MO: Security Profile” is set and gives access to
   multiple Operating Units, then the profile value “MO: Default Operating Unit”
   if set is validated against the list of Operating Units in “MO: Security
   Profile”. If the Operating Unit is included in the security profile then it
   is returned as the default value. Otherwise there is no Operating Unit
   default. Moreover, if the Profile Option “MO: Default Operating Unit” is not
   set, then there is no default Operating Unit.
