Card 2: unique ID
This string value specifies a unique ID that identifies the input interchange. For file output, this ID is included as part of the output file names to help link the acknowledgements, output transactions, and error logs to the original interchange.
The default value for this is NoUniqueID. When this value is used, an ID is generated based on the current time stamp. You must then override the generated ID with your own unique ID so you can ensure that the ID is unique and link the output to other processes. To specify the unique ID, you can use the –IE2 option, for example:
-IE2 ID1234567890
