User Exits

User exits are a type of system enhancement that were originally developed for the R/3 SD.

The SAP developer creates a special include in a module pool. These includes contain one or more subroutines that satisfy the naming convention userexit_<name>. The calls for these subroutines have already been implemented in the R/3 program. Refer Conventional SD User exits Slides

A user exit is considered a modification, since technically objects in the SAP namespace are being modified.

After delivering them, SAP never alters includes created in this manner; if new user exits must be delivered in a new release, they are placed in a new include program.

Steps Used to Implement the Project:

Step 1. Create a Project using Transaction CMOD.(LO020)

Step 2.Assign an enhancements to project that matches our requirements.

Step 3. Check the components required to implement for the enhancements and in case of function module exit note down the interface i.e import & export Parameters.

Step 4. Incase of Screen-Exits, first design the subscreen, i.e., include desired elements on the screen.

Step 5. For normal function module exits simply write code in their z includes .Check for the function modules associated with the subscreens (i.e PBO & PAI ) and write the code in their Z includes .

Step 6. For defining global data and PBO,PAI modules use zinclude in function group .

Step 7. Activate each component of the enhancement and the whole project.

Step 8.Test the transaction.

Suppose you need to find out all the user exits related to a tcode.

1. Execute the Tcode.

2. Open the SAP program.

3. Get the Development Class.

4. Execute Tcode SE84.

5. Open the Node 'Envir. -> Exit Techniques -> 'Customer Exits -> Enhancements'

6. Enter the Development class and execute.

Check out this thread..

1. Type the transaction : system->status-> <PROG. NAME>

2 open SE37 , type EXIT<PROG NAME> and press F4 to get the list of function exits available.

3. Open CMOD utilities->SAP enhancements

EDIT->All selections

4.type the function module name obtained in step 2, in fields 'component name' in 'additional selections' block. and execute.

5. The displayed list contains the enhancements names for the transaction You were looking for.

6. Create a project in CMOD and the code in default include->activate.

which gives the list of exits for a tcode

Hi,

User exits are actually empty subroutines that SAP developers provide for you. You can fill them with your own source code.

The original purpose of user exits was to allow the user to avoid modification adjustment.

How User Exits are defined?

The SAP developer creates a special include in a module pool. These includes contain one or more subroutines routines that satisfy the naming convention userexit_<name>.

The calls for these subroutines have already been

implemented in the R/3 program.

Usually global variables are used.

After delivering them, SAP never alters includes created in this manner; if new user exits must be delivered in a new release, they are placed in a new include program

The purpose behind this type of system is to keep all changes well away from program source code and store them in include programs instead.

To this end, SAP developers create various includes that fulfill the naming conventions for programs and function groups.

This naming convention guarantees that SAP developers will not touch this include in the future. For this reason, includes of this nature are not adjusted during modification upgrade.

If any new user exits are delivered by SAP with a new release, then they are bundled into new includes that adhere to the same naming convention.

The last two letters in the name of the include refer to the include that the customer should use: "Z" is usually found here.

Thanks,
