Yes… webMethods can set the priority for a message while placing it in queue…
While creating the MQ Adapter, in the MQMD Header, select msgHeader.Priority in Input Field Name… Do not set any value here unless u want to set a default priority for all the messages…
Priority ranges from 0 to 9… where 0 is the least and 9 is the highest…
Also, u can pass a value at runtime in Priority. Even though if u have some default value set in mq adapter, it will override…
Let us know if you have any questions.
