IMPORTING

fm_name = g_fm_name.

gw_options-tdnoprev = ' '.

gw_options-tdprinter = 'LOCL'.

gw_options-tdnewid = 'X'.

gw_options-tdimmed = 'X'.

gw_control-preview = ' '.

gw_control-no_dialog = 'X'.

• For all the documents

LOOP AT gi_all_data INTO gw_all_data.

write: text-006, text-007, text-008.

• Call the smarform

CALL FUNCTION g_fm_name

EXPORTING
