Is there a way to use a HL7 field value as part of the File Naming in the Business Operation FileOperation class.  I know we can do this in a custom class, but I was wondering if it could be done the default FileOperation class? Example: MSH-4 contains the value 12345 We would like to name the file 12345_YYYYMMDDHHMMSS.HL7 MSH.4 value here_%Y%m%d%H%M%S.HL7 It may not be possible, but I just want to see if anyone has any information Thanks, Kevin Brown
