What is the difference between user-exit and customer exit

Hi Madhav,

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*). 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.

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.

Hope this will help.

Generally user-exit doesn't require project..Like the sales order user exit USEREXIT_SAVEDOCUMENT_PREPARE..

Customer exit require a project to attach the exit EXIT_SAPLMRMP_010..This exit will not work unless you attach the exit to a project..
