How To Fix TR259 - No longer possible to edit application-specific messages

SAP Error Message - Details

• Message type: E = Error

• Message class: TR - Change and Transport System

• Message number: 259

• Message text: No longer possible to edit application-specific messages

What causes this issue?

It was only possible to maintain your own messages for a reservation
for generations with change authorization (reservation type F and
message type E). You could not send your own messages for other
reservations even before.
Entering your own messages for reservation type F and message type W
was also locked for Release 4.0 because
there was no need for separate messages for new reservations
the messages entered for old reservations were not maintained
(incorrect message texts, long texts that did not exist or did not have
any contents)
Maintenance of messages was only supported in internal SAP development
systems. This information is therefore not relevant for customer
systems.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

The process is terminated.

How to fix this error?

Maintain the reservation without your own messages.
