SAPScript runtime error
I have the below code.
CALL FUNCTION 'WRITE_FORM' EXPORTING ELEMENT = KOPF_TITLE WINDOW = 'MAIN'. In SAPSCRIPT
/:BOX YPOS '6' CM WIDTH '20' CM HEIGHT '2' CM FRAME 10 TW
However whenever I reached until exporting element = kopf_title, I get the runtime error. I do not understand why this runtime error is occurred as I have already declared KOPF_TITLE in SAPSCRIPT.

Anyone knows why? Please advice.
