User EXIT

User exits (Function module exits) are exits developed by SAP. The exit is implementerd as a call to a function module. The code for the function module is written by the developer. You are not writing the code directly in the function module, but in the include that is implemented in the function module.

The naming standard of function modules for functionmodule exits is:

EXIT_<program name><3 digit suffix>

The call to a functionmodule exit is implemented as:

CALL CUSTOMER.-FUNCTION ❤️ digit suffix>

To find a Exit.

Goto Transaction -- Find The Package

SMOD ~~>f4~~>Use the Package here to Find the Exits In the Package.

Else if you Want to search by Application Area wise ,

There is one more tab to find the Exits in the Respective Application Area.

Implementing the Exit-- CMOD ~~Create Projects~~Assgn your Component .

Now Run ur Transaction to Check if it Triggers.

Thats it..

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.

USER EXIT

EXIT s are nothing but the R/3 Enhancements which allows you to add your own functionality to SAP’s standard business applications without having to modify the original applications.

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.

Modifications

Any change made to an SAP object in a customer system is called a modification. Customers usually modify their systems for one of two reasons. Either they make changes to the SAP standard in order to adjust the R/3 System to their specific business needs (actual modifications), or they alter individual SAP objects in order to correct an error (as recommended in an SAP error note).

You should only modify the SAP standard if the modifications you want to make are absolutely necessary for optimizing work flow in your company. Be aware that good background knowledge of application structure and flow are important prerequisites for deciding what kind of modifications to make and how these modifications should be designed.

ABAP DICTIONARY

Table Enhancements: There are two ways that you can add additional fields to tables without modifying your system.

Append Structures:

Append structures allow you to enhance tables by adding fields to them that are not part of the standard. With append structures, customers can add their own fields to any table or structure they want.

Append structures are created for use with a specific table. However, a table can have multiple append structures assigned to it.

Customizing Includes:

If customers know in advance that one of the tables or structures delivered to them by SAP needs to have customer-specific fields added to it, an SAP application developer can include these fields in the table using a Customizing include statement.

The same Customizing include can be used in multiple tables or structures. This provides for consistency in these tables and structures whenever the itself include is altered.

Append structures allow you to attach fields to a table without actually having to modify the table itself.

Append structures may only be assigned to a single table. A table may, however, have several append structures attached to it. Whenever a table is activated, the system searches for all active append structures for that table and attaches them to the table. If an append structure is created or changed and then activated, the table it is assigned to is also activated, and all of the changes made to the append structure take effect in the table as well.

You can use append structures in ABAP programs just as you would any other structure.

Note: When you copy tables that have append structures attached to them, the fields that were found in the append structure of the original table become part of the actual body of the target table.

Some of the tables and structures delivered with the R/3 standard contain special include statements calling Customizing includes. These are often inserted in those standard tables that need to have customer-specific fields added to them.

In contrast to append structures, Customizing includes can be inserted into more than one table. This provides for data consistency throughout the tables and structures affected whenever the include is altered.

Customizing include programs are part of the customer namespace: all of their names begin with 'CI_'. This naming convention guarantees that nonexistent Customizing includes do not lead to errors. No code for Customizing includes is delivered with the R/3 standard.

You create Customizing includes using special Customizing transactions. Some are already part of SAP enhancements and can be created by using project management (see the unit on 'Enhancements using Customer Exits').

The Customizing include field names must lie in the customer namespace just like field names in append structures. These names must all begin with either 'YY' or 'ZZ'.

When adding the fields of a Customizing include to your database, adhere to same rules you would with append structures.

ABAP DICTIONARY

Field Exits:

Field exits take you from a screen field with a data element reference to a function module. Field exits can be either global or local.

Field exit function modules adhere to the following naming convention:

prefix: FIELD_EXIT_

name: <data element name>_

suffix (optional): 0 to 9, A to Z

Text Enhancements:

Possible text enhancements include customer keywords and customer documentation of data elements.

Text enhancements differ from other application enhancements in that they take effect globally in all related SAP applications after activation (global enhancements).

Customer Exits

Function Module Exits

Menu Exits

Screen Exits

Function Module Exits

Function module exits add functions to R/3 applications. Function module exits play a role in both menu and screen exits. When you add a new menu item to a standard pull down menu, you use a function module exit to define the actions that should take place once your menu is activated. Function module exits also control the data flow between standard programs and screen exit fields.

Menu Exits

Menu exits add items to the pull down menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.

SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu item’s text when activating the item in an add-on project.

Screen Exits

Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special sub screen areas on a standard R/3 screen and calling a customer sub screen from the standard screen’s flow logic.
