• Message class: SWF_XI_ADAPTER - XI BPM: Messages

• Message number: 405

• Message text: Inbound queue &1 (SMQ2) for process type &2 is not stopped

What causes this issue?

You want to change the settings for inbound processing for a process
type. This change is not permitted because the process-type-specific
queue is not stopped.

System Response

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

How to fix this error?

The short text of the error message specifies which queue must have a
stop entry. Copy the queue name and call transaction SMQ2. Start the
selection using the copied queue name. The possibilities are as follows:
The queue does not exist
Try to make the settings again.
The queue exists
Create a stop entry in the queue. Wait until no more queue entries are
being processed. Note that stopping the queue does not affect the queue
entry currently being processed; only the subsequent entries are
stopped.
When the queue is stopped, you should be able to change the setting for
the process type.
<ZH>Note the following:</> A non-existent queue may be seen as stopped
in the system, since inbound processing is locked while the settings are
being changed. Once a queue entry exists, the administrator must create
a stop entry for the corresponding queue. If, in the first case, the
system still refuses the change, this is probably because the queue
became existent or still existed in the meantime. Since new queue
entries are constantly being added, you must only change the settings
for inbound processing when the system load is low. You may have to make
several attempts to stop the queue in SMQ2 and change the setting.
