Are you talking about Subroutine and Fuctional module.

Subroutine used inside the program, but FM common to all program.

forms are like scripts/smartforms which are used to print data of standard transactions according to user requirements... these are driven by programs....

functions are programs which are written in se37 and execute for output purposes for EDI or normal output or remote output etc...

Hi,

You are talking about the Subroutine Forms or the Script/Smartforms

We define subroutines like PERFORM <name> using...

and write the code in FORM...ENDFORM.. They are Local to a Program, and they can't return a value.

(whereas the Script forms are created and changed in SE71 Tcode and for smartforms it is SMARTFORMS is the Tcode.)

Functions means function Modules are sap predefined programs which will give some output based on the input paramters.They are global programs and returns values.

reward if useful

Hi Anji Reddy Vangala,

To extrapolate the query further if the Subroutine Forms can't return a value........then can you please tell me its usage ..........

Second thing is as per my understanding we can also write our own functions in SAP and call them in the programs .........

Am I right ??

Thanks
