When you call the function module in ur ABAP program.

YOu will see Exporting and Importing .

For eg -

CALL FUNCTION 'CONVERSION_EXIT_KONPD_OUTPUT'

EXPORTING

INPUT = OUTPUT-PSPHI

IMPORTING

OUTPUT = OUTPUT-PSPID.

I am passing a value to the input field - OUTPUT-PSPHI. With this data once the function module is executed it returns me the result in the importing ie, Output and i can have the result in OUTPUT-PSPID.

I hope its clear.

Let me know for any questions.

Hi,

when tou use a FM that have a import and export parameters, you need to declare than.

Export parameters are values or variables that ou will send to the FM. Inside the FM, they will be processed.

Import parameters are values or variables that the FM will send to you, are the return of the proccess.

And sometimes you have the Changing parameters, that are variables that you send to a FM or perform and they can be changed.

CALL METHOD gr_alvgrid->set_table_for_first_display

EXPORTING

is_layout = gs_layout

CHANGING

it_outtab = ti_zcarro[]

it_fieldcatalog = gt_fieldcat

EXCEPTIONS

invalid_parameter_combination = 1

program_error = 2

too_many_lines = 3

OTHERS = 4.

In this case, you send values in EXPORTING parameters gs_layout and the method can change the internal tab ti_zcarro and gt_fieldcat.

Hope it help you.
