Diagnosis
The queues selected could not be registered specifically because theyare already registered using more general prefixes. This is merely awarning.

System Response
Queues were probably already registered that have more general prefixesthat the queues being created here. Essentially, this is not a problem.However, if these more general queues are deregistered by anotherapplication, then the necessary queues in this case would also bederegistered. The queues created here must remain registered.

Procedure
Check which queues are already registered using transaction SMQR.
Pay particular attention to queues registered in external systems withthe following prefixes:
X*, XB*, XBT*, XBQ*.
