Hi Michael, A message will be delivered to all receivers whose attributes match those of the message. When you retrieve a message via MCSOPMSG you can make no assumptions about whether the message has or hasn't been delivered to any other recipient. A DOM can potentially keep a message from being displayed on an MCS console, but in the scenario you describe it's highly unlikely to happen quick enough.
You cannot obtain a specific message id via MCSOPMSG. It is recommended that you limit the routing attributes of the EMCS console to the bare minimum required. If you are using it to issue a command and receive a response then give the EMCS console no routing attributes and use the CART on the MGCRE and MCSOPMSG. If you need to monitor for a wider range of messages then give the EMCS console only those routing attributes needed, and limit the amount of processing done on the unneeded messages obtained via MCSOPMSG. The message dataspace will be created in the console address space and will be shared by all EMCS consoles activated in your address space.
