Have you considered using a Publication node?

I don't understand.
You can put a publication node in any flow. Then it will publish the message you tell it to publish.
Most of the examples of using the publication node assume that it is in a standalone flow that will examine an incoming message for the topic, do some formatting, and then publish the message. This flow then acts as a publishing service for other flows - they can put any message to that flow's input and not know about the publication process.
But you can put a publication node in any flow.

I thought that answered your question.
What are you trying to do?
@jeff:
your post wasn't there when I started writing. |

Hi-
You can publish a message using 3 diffn options -
1. Name the topic you want to publish in the INPUT Q node in the default section
2. You can use RFH2 header to publish using mcd floder
3. In case you don't have RFH2 header you can just set the topic in ESQL Root.Properties.Topic = xxx (which is same as 1 above).
Subscription point is used in other context.

Just pipe this into publish node.
CREATE COMPUTE MODULE ProcessPublication
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
--CALL CopyMessageHeaders();
--CALL CopyEntireMessage();
SET OutputRoot.MQMD.MsgType = 1;
SET OutputRoot.MQMD.ReplyToQ = 'BROKER.REPLY';
SET OutputRoot.MQMD.Format = MQFMT_RF_HEADER_2;
SET OutputRoot.MQRFH2.(MQRFH2.Field)Version = 2;
SET OutputRoot.MQRFH2.(MQRFH2.Field)Format = 'MQSTR';
SET OutputRoot.MQRFH2.(MQRFH2.Field)NameValueCCSID = 1208;
SET OutputRoot.MQRFH2.psc.Command = 'Publish';
SET OutputRoot.MQRFH2.psc.Topic = InputRoot.XMLNS.Publication.TopicName;
SET OutputRoot.XMLNS.ArchMessage.Data = InputRoot.XMLNS.Publication.Data;
RETURN TRUE;
END;

You will have to register the subscriber with a subscription request message. That message will specify the topic. It will also specify a ReplyToQueue in the MQMD. That ReplyToQueue will be the queue that subscriptions will be published to.
So you need an MQInput node to start your subscriber.

Also make sure that you change Mikhails code so that it actually subscribes to YOUR topic, rather than to InputRoot.XMLNS.Publication.TopicName.
And make sure that you change Mikhail's code so that it specifies YOUR subscription queue, rather than BROKER.REPLY.
