Premise Long text(Note)

Hi Friends,

I am trying to update Premise Long test(Note ) through a program so far with no luck. I used FM SAVE_TEXT by passing following paramerts but I dont see any updates happening . If anyone have done this in the past please let me know

HEADER-TDOBJECT = 'EVBS'.
HEADER-TDNAME = '5000568751'.
HEADER-TDID = 'ISU'.
HEADER-TDSPRAS = 'EN'.
HEADER-TDTITLE = 'Test 678'.


DATA : TLINE TYPE TLINE,

T_TLINE LIKE TABLE OF TLINE.

TLINE-TDFORMAT = '*'.
TLINE-TDLINE = 'this is just a test'.

APPEND TLINE TO T_TLINE.

CALL FUNCTION 'SAVE_TEXT'
EXPORTING
CLIENT = SY-MANDT
HEADER = HEADER
INSERT = ' '
* SAVEMODE_DIRECT = ' '
* OWNER_SPECIFIED = ' '
* LOCAL_CAT = ' '
