Hi,

A user exit is similar to an function module. The difference is you can write your own piece of code in a user exit to fulfill your requirements. If you look into the IMPORT parameters of the User Exit all these variable in the IMPORT are inputs to your exit. All the variables in the EXPORT parameters are the ones that can be sent out of the exit. You can change all the variables that are present in bothe IMPORT and EXPORT parameters. Ex: If i have V_data in IMPORT as well as EXPORT then i can change the value of V_DATA from 1 to 2 and pass it to next step in the standard program.

Also you have TABLES in user exit. These can be inputs and output parameters. For example i can enter a few records in the tables parameter IT_TAB in one of the exits and change these records inside the USer Exit include and export the same to the next step in the standard transaction.

Hope this is helpful.... reward if useful.

Thanks,

Anil
