The Default Access Group
There are two ways an access group can be assigned to an account:
• The base package will default an account's access group based on the user who adds the account. It uses the user's default access group to do this.
• If you can conceive of a rule to assign an appropriate access group to a newly added account, you can have your programming staff introduce a user exit to the account row program to implement this rule. For example, a user exit could be developed that assigns an access group to an account based on its customer class. The name of the user-exit is AFTER-MOVE-CORR-ADD and the name of the account row program is CIPCACCR.
Warning: 
Regardless of the method used to assign an account's access group, please be aware that the user who adds an account must have access to this access group.
Note: 
Subsequent changes to an account's access group. A user may change an account's access group to any access group to which they have access.
