what is diff b/w user exits and cutomer exits
Answer Posted / dushyanth kumar
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
Customer exit - 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.
User exits are basically modifications done to the std. pgm
for whic u need to have access code,this is not reccomended
in sap as during upgradation none of the mod. will come
thru.
In contrast customer exits are enhancements done to the
std pgm in the space provided by sap so that during
upgrading versions this also will be available.
Customer exits types
