How To Fix AD040 - & is reserved for &

AD040 - Overview

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 040

• Message text: & is reserved for &

What causes this issue?

Both an active and a revised version of the selected object exist. The
revised version is locked by another user, so you cannot obtain update
authorization for this object. This is not a temporary system lock
(i.e. the user is currently maintaining this object), but a permanent
reservation of the revised version.

System Response

Since an active version of the object also exists in addition to the
revised version, the active version is displayed with a message
explaining that the revised version is locked.

How to fix this error?

Only the user currently maintaining the revised version can remove this
lock by activating it, resetting it or explicitly releasing the object
for maintenance by all other users with the 'unlock' function.
