Enhancements in SAP table

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

REPORT ZDEMO_EXAMPLE.

TABLES: MODSAP, MODACT.

PARAMETERS: INPUT1 LIKE MODSAP-NAME DEFAULT ' ',
INPUT2 LIKE MODSAP-TYP DEFAULT ' ',
INPUT3 LIKE MODSAP-MEMBER DEFAULT ' '.

DATA: SEARCH1 LIKE MODSAP-NAME,
SEARCH2(3), " like modsap-typ,
SEARCH3 LIKE MODSAP-MEMBER.

CONCATENATE: '%' INPUT1 '%' INTO SEARCH1,
'%' INPUT2 INTO SEARCH2,
'%' INPUT3 '%' INTO SEARCH3.

SELECT * FROM MODSAP WHERE NAME LIKE SEARCH1
AND TYP LIKE SEARCH2
AND MEMBER LIKE SEARCH3.
SELECT SINGLE * FROM MODACT WHERE MEMBER = MODSAP-NAME.
WRITE: /10 MODSAP-NAME, 30 MODSAP-TYP, 45 MODSAP-MEMBER, 70 MODACT-NAME.
CLEAR : MODSAP, MODACT.
ENDSELECT.

IF SY-SUBRC NE 0.
WRITE : /'Not found'.
ENDIF.

END-OF-SELECTION.
CLEAR: SEARCH1, SEARCH2, SEARCH3.

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

Enhancements (User Exits & Customer exits)

Enhancements:

The enhancement concept allows you to add your own functionality to SAP's standard business applications without having to modify the original applications.

To modify the standard SAP behavior as per customer requirements, we can use enhancement framework.

There are different ways to implement custom functionality in the SAP standard code.

ex: User exits,

customer exits,

BADI etc.

User exits can be found in the following ways:

Go to Object Navigator (SE80),

select Package and put VMOD (Application development R/3 SD customer modification) and

press enter.

You will find all the includes for user exits in SD.

User-exits are empty subroutines that SAP Developers have provided for you.

You can fill them with your own source code. Technically this is a modification.

All User exits start with the word USEREXIT_...

FORM USEREXIT_XXXX....
INCLUDE ZZUSEREXIT.......
ENDFORM.

customer exits:

SAP creates customer exits for specific programs, screens, and menus within standard 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.

Customer exits are nothing but a include in customer name space will be provided in the function module which starts with CALL CUSTOMER.

Advantage:

- They do not affect standard SAP source code.
- They do not affect software updates.

Disadvantage:
- Customer exits are not available for all programs and screens found in the SAP System.

- You can only use customer exits if they already exist in the SAP System.

Types of Customer Exits
1. Function Module exits
2. Screen exits
3. Menu exits

1. Function Module exits:

Function module exits are exits developed by SAP.

The exit is implemented 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.

Format: CALL CUSTOMER-FUNCTION '910'
The naming standard of function modules for function module exits is:
EXIT__<3 digit suffix>

2. Screen exits:

Allow customer to add fields to a screen via a sub screen in an SAP program. The sub screen is called within the standard screen's flow logic.

Format: CALL CUSTOMER-SUBSCREEN CUSTSCR1

3. Menu exits:

Menu exits allow you to add your own functionality to menus.

Menu exits are implemented by SAP and are reserved menu entries in the GUI interface. The developer can add his/her own text and logic for the menu.

Function codes for menu exits all start with "+".
Format: +CUS (additional item in GUI status)
