How do I combine timestamp and message control ID?

Hello,

I'm trying to create a file name in my destination called something like {timestamp yyyymmddhhmmss)_{value from MSH.10.1}.hl7



Example:

2014112208102311_123456.HL7



In the destination Tab I tried to put ${date.get('yyyyMMddHHmmss')}.hl7 and that works to create the file name but I can't get the MSH.10.1 (Message Control ID) to work.



Does any one have any ideas?



Thanks,



Rubi
