Issue in maintaining Long Text in Message Class

Question

Hi
For Note implementation 1413492, I have to maintain long text, when I click on Long Text , I get a pop-up Create Modification , with 2 options for Template Type (1) Original Text (2) Template (With Headers)
Can anyone let me know how to proceed further, whatever name I give for the Modification, I am getting Error Message saying 'Enhancement Name violates the namespace convention (Note 989653)', I have tried unchecking the Self Explanatory check box as well, but still I get the same error message.
Below is the Long text I have to maintain class FR, message number 533
7. Create new error messages in the message class FR:
Call transaction SE91, enter the message class FR, and choose "Display" and
then "Change". Enter the following new messages:
Message Message short text:
533 Error while calling RFC destination
534 Contract Accounts Receivable and Payable is not installed in the
system
535 For company code & there were & data records transferred from
FI-CA
536 Error during data transfer from FI-CA for company code &; error
text:
Set the "Self-explanat'y" indicator for messages 535 and 536.
Enter a long text for messages 533 and 534:
Long text FR 533:
CAUSE
An error occurred when testing the RFC connection to Contract Accounts
Receivable and Payable. The message text is:
&V1&&V2&&V3&
SYS_ADMIN
Check the settings of the RFC destination &V4&.

Hi Ryan,
Extract from note 989653;
Note:                                                                               
The name of the modification object must start with:                                                                               
o  'Z'/'Y', or                                                                               
o  the customer namespace available in the system (TRNSPACE table).                                                                               
Otherwise, message 645 will appear because the SAP namespace is not   
permitted.                                                                               
My suggestion would be to start the name with a Z.
Regards,
Nick
