A company wants to generate a Sales Order Confirmation that prints both header data (from VBAK: Sales Order Number, Customer, Date) and item details (from VBAP: Material, Description, Quantity).
The business expects a simple printable document that can be given to customers.

Since this is a text-heavy output with minimal graphics, the customer chooses SAPscript as the form technology.

ABAP Driver Program → Fetch data (VBAK/VBAP)

SAPscript Layout Set (SE71) → Windows + Paragraph Formats

Final Output → Printed / Spool / PDF

REPORT zsd_sapscript_driver.

TABLES: vbak, vbap.

DATA: it_vbak TYPE vbak,
it_vbap TYPE TABLE OF vbap,
wa_vbap TYPE vbap.

START-OF-SELECTION.

“Fetch Sales Order Header
SELECT SINGLE * INTO it_vbak
FROM vbak
WHERE vbeln = p_vbeln.

IF sy-subrc <> 0.
MESSAGE ‘Sales Order not found’ TYPE ‘E’.
ENDIF.

“Fetch Sales Order Items
SELECT * INTO TABLE it_vbap
FROM vbap
WHERE vbeln = p_vbeln.

CALL FUNCTION ‘OPEN_FORM’
EXPORTING
form = ‘ZSALES_ORDER’ ” SAPscript layout set
language = sy-langu.

“Print Header Window
CALL FUNCTION ‘WRITE_FORM’
EXPORTING
element = ‘HEADER’ ” SAPscript text element
TABLES
lines = it_vbak.

“Print Items
LOOP AT it_vbap INTO wa_vbap.

lines = wa_vbap.
ENDLOOP.

“Close Form
CALL FUNCTION ‘CLOSE_FORM’.

Key Notes

• Layout set is created in SE71 (e.g., ZSALES_ORDER).

• Text elements HEADER and ITEMS must be defined inside the layout set.

• Data (from VBAK/VBAP) flows from ABAP → WRITE_FORM → Windows in layout.
