USER EXIT

[Former Member]

Hello SAP guys,

As a SD consultant what am i suppose to know about USER EXITS.I know these r certain programs which gets triggered when certain activities ( for eg -a user exit may be there which checks certain criteria before sales doc is saved) takes place.

So as a SD consultant what shd i know about USER EXITS.

Do we need to configure these??

Do we also have to create USER EXITS or is it the job of the ABAPers.

Thanx,

Rahul

Hi,

User exits are enhancement spots provided by SAP to enhance the logic as per the requirement.

As a SD consultant you should know be able to decide which user exit should be used in different situations (as per the requirement).

You dont configure this. You would need user exit name so that you could use it for functional specification document. You should also know what logic you can use to achieve the requirement. ABAPer would use this exit and introduce logic as per the requirement.

SAP provided user exits for different situations. You will ask the ABAPer to implement user exits as per the requirement.

Certain application like SD still provide this form of enhancement using userexit but this practice is no longer being followed for newer extensions

instead they are using EXITs which come bundeled in enhancement packages . Neverthiless existing USEREXITS will be supported by SAP an all the newer versions of SAP.

User exit - A user exit is a three character code that instructs the system to access a program during system processing.

SXX: S is for standard exits that are delivered by SAP. XX represents the 2-digit exit number.

UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number

we dont have to configure user exit.It is the job of ABAPERS.

we need to search the userexit available.

Types of Exits

There are several different types of user exits. Each of these exits acts as hooks where you can attach or "hang" your own add-ons.

Menu Exits

Menu exits add items to the pulldown 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 itemu2019s 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 subscreen areas on a standard R/3 screen and calling a customer subscreen from the standard screenu2019s flow logic.

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. SAP application developers create function module exits by writing calls to customer functions into the source code of standard R/3 programs.

These calls have the following syntax:

CALL CUSTOMER-FUNCTION u2018001u2019.

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. Example: The data element BBBNR identifies a companyu2019s 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.
