To output SAPscript forms, in the print program you must always start the output with OPEN_FORM and end it with CLOSE_FORM. The function module OPEN_FORM initializes the SAPscript composer and opens the specified form for subsequent output. The system combines all output for this form up to the CLOSE_FORM to one print request. If CLOSE_FORM is missing, nothing will be printed.

To output data in a form, you must use the SAPscript function modules WRITE_FORM, WRITE_FORM_LINES, and CONTROL_FORM. You can use these function modules any number of times in any order between opening and closing a form.
