hi priya,

function group: Function groups are containers for function modules. You cannot execute a function group. we can also define it as GROUP OF ALL RELATED FUNCTIONS

function modules: Function modules are procedures that are defined in special ABAP programs only, but can be called from all ABAP programs. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench

hi,

Function modules are ABAP routines that are administered in a central function library. They apply across applications and are available throughout the system. You must assign function modules to a function pool that is called a function group. A function group is nothing but a container for the function modules. Now create a function group and then a function module, which you can use for the next exercise steps.

function group can be create through object navigator, se80.. and function module can be created using se37.

plz reward points if helpful..
