Hi Anthony,
Two things you can check:
1. Ensure the notification number you are passing is valid, i.e. it has the requisite number of leading 0s (apply CONVERSION_EXIT_ALPHA_INPUT to ensure to the field notif_no before passing it to ls_header)
2. In the function module to SAVE_TEXT - INSERT should be 'X' not 'x'
Please check.
