FORM f_check_date USING p_date TYPE sy-datum.

CALL FUNCTION 'DATE_CHECK_PLAUSIBILITY'

EXPORTING

date = p_date

EXCEPTIONS

plausibility_check_failed = 1

OTHERS = 2.

endform.

PERFORM f_check_date using <pass_req_date - from date.>

PERFORM f_check_date using <pass_req_date - to date.>

Thanks

Vijay

Hi,

While you create your function module. Specify IMPORT and EXPORT parameters with corresponding types.

In your program when you call the function module via Patterns, the function call will be displayed with EXPORTING and IMPORTING parameters.

You have to pass in the EXPORTING parameter the IMPORT TYPE declared in your function module.

The IMPORTING parameter in the function is the value it returns which you need to store in an appropriate variable.

DATA: ex_var TYPE C.

DATA: im_var TYPE C.

CALL FUNCTION 'my_own_function' "using patterns

EXPORTING

import_var_defined_in_fm = ex_var.

IMPORTING

export_var_defined_in_fm = im_var.

hi anand,

' Using' is one of additional that we can use with the perform function..that is like pass by value in other languages. if u use 'changing' means its like pass by reference
