Advantages: No programming knowledge is required.
Disadvantages: Depending on the complexity of the database tables, it may not be easy for the user to select the necessary data correctly.
Functional Areas - By creating functional areas, we can initially select this data. This ensures that the data is presented to the ABAP Query user in a meaningful way to accomplish the task, and that only the data that the user may use is presented.
User Groups – A user group is a collection of users that work with about the same data and carry out similar tasks. The members of a user group can use all programs (queries) created by any user of the group. Changes to such a program are at once visible to all users. This ensures that all members of a user group use the same evaluation programs.
ABAP Query: It consists of three components – queries, functional areas and user groups. The functional areas provide the user with an initial set of data in accordance with the task to be accomplished. All users must be members of at least one user group. All members of one user group can access the same data as well as the same program (queries) to create lists.

The R/3 System synchronizes simultaneous access of several users to the same data records with a lock mechanism. When interactive transactions are programmed, locks are set and released by calling function modules (see Function Modules for Lock Requests). These function modules are automatically generated from the definition of lock objects in the ABAP Dictionary.
