CLOSE_FROM
 
To start printing a form we must use OPEN_FORM and in the end we should use CLOSE_FORM to complete the spool request.
 
Function modules in detail.
 
OPEN_FORM function module
This function module should be called first before any printing can take place , here we specify the name of the form and the print language.
 
CALL FUNCTION 'OPEN_FORM'
EXPORTING
   DIALOG         = 'X'
   DEVICE         = 'PRINTER'
   FORM            = form name
   LANGUAGE   = SY-LANGU
*  OPTIONS      =
EXCEPTIONS
   CANCELLED  = 1
   DEVICE          = 2
   FORM            = 3
   OTHERS        = 11
.
 
IF SY-SUBRC NE 0.

ENDIF.
 
In the above function module the parameter
FORM      = Name of form
DEVICE    = PRINTER (print using spool),TELEFAX (fax output)
                   SCREEN (output to screen)
OPTIONS = It is a structure of type ITCPO and it controls the various
                   attributes like number of copies , print preview etc.
 
START_FROM function module
 
This function module is called if we want to use different forms with similar characterstics in a single spool request,it must be closed by END_FORM function module.

This function module is used to write text in a window in the form using
text elements (/:E element). We can specify whether the text is to be appended , replaced or added and in which portion of the window it will be printed i.e TOP, BOTTOM ,BODY. In this function module actual printing takes place.

printed . WINDOW specifies which window of the form to be print in.
TYPE specifies the output area of the window TOP,BOTTOM,BODY.
FUNCTION specifies whether the text is to be appended , replaced or added.
