Accounts Information contains the masters. Each master has Create, Alter and Display functions.
Single Group option is useful when you wish to work on one Group at a time. Multiple Group option is very useful when you are working on many sub-groups at a time and saves a lot of time. Once a sub-group is created, it behaves exactly like a Group.
The Create option is used to create new masters.
The Display option is used to view the Master information. Master information cannot be modified in Display mode.
The Alter option allows you to view and make the necessary changes to the master information. This does not allow the creation of masters.
