A subroutine can only be called from a program while a function module can be executed as a standalone..

hi ,

Function module existed in global lever where as subroutine is related to program.

and exceptions rising is also possible in function module but not in subroutine.

Hi,

A Subroutine can only be called within a program, will be destroyed/out of scope at outside the program, cannot be called from any other program.

Where as a Function module is availabe in SAP repository and can used in any no. of programs. It is having Scope in entire SAP repository. It can be declared globally and can be used in any program.

FM's are global. Also client independant. But Sub routines can not.

Cheers.

Function Module can be run individually using SE37 transaction.But subroutine cant be run individually.

you can't catch exceptions in subroutines. But in Function modules you can.

Hi,

subroutine is program specific logical group of abap sentence which has using changing and tables as parameters which achieves a particular functioanlity.

FM is at global levels means u can call same FM in different programs and parameters are import export, tables and exceptions etc. u have to pass import and export parameters to FM.

Also in case of subroutines u can call it from other program like,

Perform sub_name in program ( Program name ) if found.

Subroutines cannot be called in different server

where functional module can be remotely called in another server.....

Hop this is also a big difference...
