AP Remittance Advice Header Title

I want different header printed in the email body of the AP remittance advice.

The standard message for AP_APPEF_HEADER_TITLE is "The following payment has been remitted:"

I want this to be changed to "The following payment has been remitted to the bank"

I tried changing the message body using application developer message screen. The system does let me save it. When I confirm the payment batch, the remittance email goes out with the old message. Is there any other place this needs to be modifed along with applciation developer messages screen.

Oracle version 11.5.10.2

Thanks

Dolly
