Answer 1

Declare the gv_orderid in modulepool program.
And Declare the parameter as import parameter in smartform.
CALL FUNCTION  lv_form
   EXPORTING
*   ARCHIVE_INDEX              =
*   ARCHIVE_INDEX_TAB          =
*   ARCHIVE_PARAMETERS         =
*   CONTROL_PARAMETERS         =
*   MAIL_APPL_OBJ              =
*   MAIL_RECIPIENT             =
*   MAIL_SENDER                =
*   OUTPUT_OPTIONS             =
*   USER_SETTINGS              = 'X'
     i_input                    =  gv_orderid
* IMPORTING
*   DOCUMENT_OUTPUT_INFO       =
*   JOB_OUTPUT_INFO            =
*   JOB_OUTPUT_OPTIONS         =
* EXCEPTIONS
*   FORMATTING_ERROR           = 1
*   INTERNAL_ERROR             = 2
*   SEND_ERROR                 = 3
*   USER_CANCELED              = 4
*   OTHERS                     = 5
