    Purpose

    To introduce the techniques of enhancement in standard SAP system. SAP creates customer exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.

    Use

    They do not affect standard SAP source code.

    When you add new functionality to your SAP System using SAP’s exits, you do not alter the source code of standard SAP programs in any way. The code and screens you create are encapsulated as separate objects. These customer objects are linked to standard applications, but exist separately from SAP’s standard software package.

    They do not affect software updates.

    When you add new functionality to your SAP System using SAP’s exits, your objects (called customer objects) must adhere to strict naming conventions. When it comes time to upgrade a to a new software release, customer objects’ names ensure that they will not be affected by any changes or new additions to the standard software package.

    Challenges

    Customer exits are not available for all programs and screens found in the SAP System.

    About the option of abap qurey with logical database, you can only append tables to the existing relation but delete any table(although there are any tables you don't want),

    another option you proposed can join any tables you want.
