Hi,

Step by step procedure for creating Screen Exits

PART A: Search for the screen exit.

1. A screen exit is a way to add a sub-screen and corresponding functionality to an SAP transaction. The first step is to navigate to the screen where you want to attach menu exit.

2. Go to the field list of that screen through system -> status or F1 -> Technical details and look for fields that have subscreen as the field type for that particular screen. These are the area's on the main screen which can be enhanced.

PART B: Creating your own subscreen.

3. Identify the enhancement and its component that has the provision for creating the screen exit for that particular screen.

Note A: To know more about how to identify the enhancement, refer to the document on Locating User Exits.

Note B: All SAP provided subscreen’s may not have the scope for enhancement. There are a limited number of transactions which has scope for screen exit. Refer to Annexure A for details.

4. Include the Enhancement in your own project through transaction CMOD.

5. Go to Enhancement Components and double click on the component name.

6. It will take you to the screen attributes for that particular subscreen.

• The screen type should be subscreen.

• Maintain the size of the subscreen through Lines/Columns attribute. This should correspond to the size of the subscreen mentioned in the main SAP screen.

• The development class for the subscreen should be the development class for the project.

7. Create the subscreen using the fullscreen editor.

8. You can add your own modules in the subscreen’s flow logic. However, one has to be careful regarding data transfer between the main screen and the subscreen. For more details refer to R/3 On-line Help.

9. Generate the screen.

PART C: Activating the project

10. Use the back button to navigate back to the project enhancement main screen.

11. Activate the project.

Locating User Exits

Before you can add functionality to a SAP system, you need to be able to locate the appropriate user exits. SAP has provided around 2000 user exits.

Searching from transaction CMOD

Searching from the Application Hierarchy

Making your own customized search

Keep in mind that you must first search for an enhancement. Once you find an enhancement, you can display its components -- the actual user exits. Then you need to include the enhancement containing the required user exit as a component in your own project.

Method #1: Using Transaction CMOD

• Transaction CMOD contains search functionality to help locate enhancements.

• Selecting the "Utilities -> SAP enhancements" menu path in transaction CMOD will take you to an enhancement selection screen .

• You can limit the search for enhancements based on:

Enhancement name

Development class

• After clicking on the ‘Execute’ pushbutton (or ‘F8’) on the selection screen, the system will display a listing of the development classes that contain enhancements (see graphic above).

• From this listing, you can double-click a development class to display its enhancements.

• If you have clicked on the ‘Display components’ pushbutton on the selection screen (see graphic on previous page), the components of each enhancement will automatically be displayed.

Remark: To use this search method one must either know the part of the enhancement name or the development class. But if one looks at SAP’s naming convention for user exits (see note below), the screen numbers/program names/ function codes/etc are contained in the components name and there is no scope for that in selection options. Also one cannot restrict the search to only one type of exit.

Method #2: Using SAP Application Hierarchy

• Selecting the "Overview -> Applic. hierarchy -> SAP" menu path in the ABAP/4 Development Workbench will take you to a listing of all standard SAP applications and components .

• To locate a user exit for a particular application, follow these steps

from the SAP Application Hierarchy:

• Select the appropriate application by single clicking on it.

• Choose the "Edit Sel./desel. subtree" menu path.

• Click on the ‘Repository Infosys.’ pushbutton.

• This will take you to the ABAP/4 Repository Information System.

• Double click on the ‘Environment’ branch.

• Double click on the ‘Customer enhancement’ branch.

• Double-click on the ‘Customer exit’ branch.

• This will take you to the customer exit (or enhancement) selection screen with the appropriate development class for the application selecting on the Application Hierarchy.

• Click on the ‘Execute’ pushbutton.

• This will take you to a listing of all enhancements that meet the selection criteria.

From this listing, you can display the components of each enhancement and the documentation. You will be taken automatically to transaction SMOD from the ABAP/4 Repository Information System.

Remark: To use this one must have knowledge about the application hierarchy to which that particular enhancement belongs. Also one has to explode individual enhancements to identify weather the component is contained in that enhancement.

Like previous method, there is no scope for selection option on the components name.

Method #3: Writing a small report program

The details about projects, enhancements and components are contained in two SAP tables:

MODSAP: containing enhancement name, type of exit and component

MODACT: containing project name and enhancements

Thus by writing a report program to retrieve data from these two tables, you can customize your search requirements. Code for one such sample program is attached in annexure A and the corresponding transaction code to execute this program is YSMD .

Using this you can list all components that match a particular string like the program name or the function code as well as search for only one type of exit.

NOTE: SAP’s naming convention for user exits-

• Program/Function exits : EXIT_AAAAAAAA_nnn where

AAAAAAAA stands for the program name which contains the exit and

nnn is a SAP assigned number starting from 001

• Menu exits : AAAAAAAA+XXX where

AAAAAAAA stands for the program name which contains the exit and

+XXX is the name of the function code contained in the menu item

• Screen Exits : AAAAAAAA_nnnn_BBBBBBBB_CCCCCCCC_mmmm where

AAAAAAAA : calling program name

nnnn : calling screen number

BBBBBBBB : area

CCCCCCCC : called program name

mmmm : called screen number

When you look into se16 you just get the number of rows for this client, while db02 shows the table size over all clients. Therefore the tables size didn't match my calculations.
