Deregistering a Queue
You want to deregister a queue.
To deregister a registered queue, use transaction SMQR, or call the function module QIWK_UNREGISTER (single or generic, for example, BASIS_TEST_*).
You can deregister a queue even if it is already registered in SMQR with a “wild card” (that includes your queue). You can also call the function QIWK_UNREGISTER with the parameter LIMITED ‘X’.
