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 subscreenu2019s 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.

u2022 The screen type should be subscreen.

u2022 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.

u2022 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 subscreenu2019s 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

u2022 Transaction CMOD contains search functionality to help locate enhancements.

u2022 Selecting the "Utilities -> SAP enhancements" menu path in transaction CMOD will take you to an enhancement selection screen .

u2022 You can limit the search for enhancements based on:

Enhancement name

Development class

u2022 After clicking on the u2018Executeu2019 pushbutton (or u2018F8u2019) on the selection screen, the system will display a listing of the development classes that contain enhancements (see graphic above).

u2022 From this listing, you can double-click a development class to display its enhancements.

u2022 If you have clicked on the u2018Display componentsu2019 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 SAPu2019s 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

u2022 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 .

u2022 To locate a user exit for a particular application, follow these steps

from the SAP Application Hierarchy:

u2022 Select the appropriate application by single clicking on it.

u2022 Choose the "Edit Sel./desel. subtree" menu path.

u2022 Click on the u2018Repository Infosys.u2019 pushbutton.

u2022 This will take you to the ABAP/4 Repository Information System.

u2022 Double click on the u2018Environmentu2019 branch.

u2022 Double click on the u2018Customer enhancementu2019 branch.

u2022 Double-click on the u2018Customer exitu2019 branch.

u2022 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.

u2022 Click on the u2018Executeu2019 pushbutton.

u2022 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: SAPu2019s naming convention for user exits-

u2022 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

u2022 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

u2022 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
