Answer 1

see,
Userexits can be found in number of ways:
1) To find userexits in SD module , goto object navigator(SE80) and select
    development class from the list and enter VMOD in it. All of the userexits in SD are contained in the development class VMOD. Press
enter and you will find all the includes which contain userexits in SD for
different functions like PRICING, ORDER PROCESSING etc. Select the userexit according to the requirement and read the comment inserted in it
and start coding .
2)The other method of finding userexit is to find the word USEREXIT in the
associated program of the transaction for which we want to determine userexit using SE38.
3)The other method of finding userexits is to find the include in case of SD/MM applications where the userexits are located ,this can be found in the SAP reference IMG generally in the subfolder under SYSTEM MODIFICATION.
