Unable to add code in USEREXIT_SAVE_DOCUMENT_PREPARE in include MV45AFZZ

Question

Hi Experts,
I need to add some custom codes in USEREXIT_SAVE_DOCUMENT_PREPARE
-> I opened the include program MV45AFZZ in display mode
-> Edit -> Enhancement operations -> Show implicit enhancement operations.
On the status bar it displays an information "Creating of enhancement supported only for line length > 72" 
inside form USEREXIT_SAVE_DOCUMENT_PREPARE I right clicked -> selected enhancement implementations -> create.
and now I get the same message On the status bar "Creating of enhancement supported only for line length > 72"  .
how do I add a piece of code here.
I can't type in under USEREXIT_SAVE_DOCUMENT_PREPARE.
Give a solutions experts.
Regards,

Hi ,
I believe we need not use the enhancement framework in MV45AFZZ
Go to SE38 -> MV45AFZZ -> change mode
Keep the mouse on the user exit USEREXIT_SAVE_DOCUMENT_PREPARE
On the tool bar click on "Insert" icon ->icon description: Insert Line Area
ControlShiftF8....
An editable area will be displayed with a
*{   INSERT         &$&$&$&$                                          1
*---> Write code here
*}   INSERT
Save and activate the code
Hope it helps
Regards
