hi,

check this

Exits are basically the hooks whcih SAP has provided to add your own code. There are two types of Exits:

1. Customer exits: Implemented as Function Modules within z includes. Anybody can change it and no access key is required.

2. User Exit: Implemented as subroutines within includes (any include except y or z includes). You need access for the specific include and then you can any subroutine (user exit) within that Include.

BADIs are the enhanced version of user exits where the same logic is implemented via classes and object (OOP)

Enchancement point is the latest once introduces with ECC6.0 . Not very sure about that but you can change it without any access key.

Please go through the following link which will help you understand the exits in a much better way:

Using Field Exits

Field exits allow you to create your own programming logic for any data element in the Dictionary. You can use this logic to carry out checks, conversions, or business-related processing for any screen field.

The data element BBBNR identifies a company’s international location number. You might want to set up your R/3 System so that all international location numbers are larger than 100. The field exit concept lets you create a special function module that contains this logic.

You assign the special function module to the data element BBBNR. You then assign the module to any programs and screens in which users can add new international location numbers. When you activate your field exit, the system automatically triggers your special routine whenever a user enters a company location number.

To create your own logic for a particular data element, proceed as follows:

1. Enter the Project management transaction by choosing Utilities

2. ® Enhancements ® Project management from the ABAP Development Workbench menu. Choose Text enhancements

3. ® Field exits.Choose Field exit

4. ® Create.Enter the name of data element.

5. Choose Continue.

The system takes you into the Function Library and suggests a name for your function module ( FIELD_EXIT_BBBNR ). You should use this name.

6. Create the source code and, if needed, global data for your function module.

7. Activate the function module.

After you have created the processing logic for your field exit, you must assign the exit to one or more programs and screens. This assignment tells the system which screens to trigger your function module on.

If your processing logic checks naming conventions for a certain field, for example, you might want to trigger the field exit module only on screens where new data can be written to the database. If another screen allows you to display data only, then you can leave out the special function module call. To assign your field exit module to one or more screens, proceed as follows:

1. Select the field exit.

2. Choose Assign prog./screen.

3. Enter the name of the program and the screen number.

4. Choose Save.

For some fields, you might want to trigger a different processing logic on different screens. You can trigger screen-specific logic by allocating a field exit identifier when you make your screen assignments. A field exit identifier can be any number or letter. The field exit identifier tells the system to trigger the function module that has this identifier in its name.

Hi,

6. Create the source code and, if needed, global data for your function module.

7. Activate the function module.

1. Select the field exit.

2. Choose Assign prog./screen.

3. Enter the name of the program and the screen number.

4. Choose Save.

You create a field exit for the data element BBBNR. You make the following exit and screen assignments:

Field exit

Program

Screen

SAPMI0IA

2300

SAPMI0IA

3450

If a user makes an entry into the BBBNR-related field in screen 2300, the system triggers the function module called FIELD_EXIT_BBBNR_1 . If the user makes the same entry in screen 3450, the system triggers the function FIELD_EXIT_BBBNR_2 .

After you have created one or more function modules and assigned them to programs and screens, you need to activate the field exit. Choose Field exit ® Activate. The system will trigger the processing logic in your function modules according to the screen assignments you made.
