let me explain plssss

Answer 1

Hi,
1) Exits are the place where you can ehnace or modify the standard or create custome object where are not delivered by sap in standard format.
Normally in exit you write you logic for enhancement and modification.
2)
Customer exit --tc SMOD.
"The R/3 enhancement concept allows you to add your own functionality to SAP’s standard business applications without having to modify the original applications. 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."
Customer exits are implemented in Z-includes and are ENHANCEMENTS to the system.
User-exits were firstly intended to be developed for the SD module. You make your coding in includes in SAP namespace (e.g MV*). <b>That's why, user exits are MODIFICATIONS to the system. In includes for user exits there are empty subroutines ( generally with the name convention "userexit_...") and you code using global variables of the main program.</b>
TC CMOD
the exits are:
<b>EXIT_SAPLRSAP_001 for transactional data
EXIT_SAPLRSAP_002 for master data
EXIT_SAPLRSAP_003 for texts
EXIT_SAPLRSAP_004 for hierarchies</b>
But, generally developers use these terms without this distinction. So, someone may mean a "customer exit" when (s)he says "user exit" or vice-versa.
And SAP Exit are standard business content exit..like variable 0dat in reporting.
Hope i m clr.
Rgds,
San!
