Message type: E = Error
Message class:  STRALAN_MSAG - Language Transport Messages 
Message number: 027
Message text: Language locked, you cannot perform this action
When an action is executed on a language, an ENQUEUE entry is used to
lock the language. This prevents multiple actions (for example, an
import and a supplementation) from being executed at the same time on
the same language.
The system attempts to lock the language befor you execute another
action on the language. If it cannot lock the language, this message
appears.
Wait until the action that is locking the language has finished.
In rare cases (for example, if the system or a program crashes), a lock
may remain, even though no action is active.
If this is the case, you must remove the lock manually. To do this, use
Transaction SM12 and search for locks on the table T002C. Make sure
that no action is active before you remove the lock. To view the
language transport actions, go to the Transaction SM37 and search for
jobs that start with the prefix SAP-LANGUAGE.
