Publishing a Topic with a custom Message Type

[thebird]

Hi,

I have a Publish job using MQ Connector Stage in Client mode - set to use Publish/Subscribe mode, publishing records/messages with a Topic.

When the Message Type is set to Default i.e, Datagram - everything works well and the messages are routed to the subscription queues correctly by MQ. But when i set the Message Type as a Custom Value (say "99999999") - the published messages are being sent to the Dead Letter Queue by MQ with the error - MQRC_MSG_TYPE_ERROR.

Wonder what is happening? Can we not use a Custom Message Type while using the Pub/Sub mode?

Appreciate any help on this issue.

Thanks!
