Hi Ali,

Go through the following:

When we are passing parameter by reference, then a separate copy will not be created. If we are passign by value, a separate copy will be created.

1. Pass by value and pass by reference ( getting result )

a) Pass by value

PERFORM subr USING a1 a2 a3 a4 a5

Click for example: http://help.sap.com/saphelp_47x200/helpdata/en/9f/db979d35c111d1829f0000e829fbfe/frameset.htm

b) Pass by reference

PERFORM subr CHANGING a1 a2 a3 a4 a5

Click for example Example: http://help.sap.com/saphelp_47x200/helpdata/en/9f/db979035c111d1829f0000e829fbfe/frameset.htm
