Changing tab will have variables which you pass to the FM when you call it and the same variables are returned with a CHANGED value based on the processign logic.

Hi,

CHANGING can be used to pass the value from the calling program..And use the same parameter to change inside the FM and send it back..

Example..

Create a FM which has only CHANGING parameter..

The parameter name is CH_DATE TYPE SYDATUM.

FUNCTION ZFUNCTION.

CH_DATE = CH_DATE + 1.

ENDFUNCTION.

Calling program

DATA: V_DATE TYPE SYDATUM.

V_DATE = SY-DATUM.

CALL FUNCTION 'ZFUNCTION'

CHANGING

CH_DATE = V_DATE.

WRITE: / V_DATE.

Thanks,

Naren

Hi ,

The changing tab as the name suggests is basically used to pass those variables/structures whose value is passed to the FM , some processing takes place on it and the new value is passed back to the program.

I did not get the meaning of the second questio, could you please explain more.
