It's what I said, you did a modification of the standard (as shown by the comment line *{ INSERT RFIK90002). Your code is not an enhancement implementation, it's a enhancement option/section (which has a default code, but which can be overriden with a enhancement implementation).
Consequently, you just need to remove the code by modifying the code directly, you don't need the "spiral" icon at all here.
If you're asked a modification key, that means there was an upgrade of your system (modification key is dépendent of installation number/release number), and you need to ask one to your admin (or via the Service Market Place in the SSCR section if you're authorized).
