I have a flat file coming into PI via JMS adapter (MQ) and going out on a File adapter (NFS). We would like to keep the file name consistence throughout the transaction. While coming from MQ our sender is sending the filename in one of the MQ Headers (JMSCorrelationID). We are trying to figure out how to read the file name from the MQ header and send it to the file adapter. Please let us know any other suggestions.
