Subject Re: Set priority to files based on date time value stored on attribute
Date Thu, 08 Jun 2017 12:28:21 GMT
Hi Pierre,


After converting those date time format in to integer (using expression
language),I can able to process the file as per the requirement
by setting those integer values to the priority attribute and process those
files based on that priority.

Thanks for your guidance


Regards,
Manoj kumar R
