Currently, we do not have a way to generate a UUID within GoAnywhere implicitly. We do allow you to utilize HTTP calls and retrieve values from a Web Service or connect to a Database and retrieve values.
One option is the following link: http://www.fileformat.info/tool/guid.ht ... ormat=text
It will allow you to connect and return a UUID value. This can be done interactively within your GA Workflow, to use while defining your UTID needed for the IRS transfer.
If you are installed on Linux, this link:http://linux.die.net/man/1/uuidgen
Will generate a UUID for you by calling a command line utility.
If you're using Windows and have Powershell:http://blogs.technet.com/b/heyscripting ... shell.aspx
or MAChttps://developer.apple.com/library/mac ... gen.1.html
But, I believe you also have options to create these values using your DB. Since you work on the iSeries, you should have access to the DB2 database. This means, you could generate a DB2 Function to create the unique UTID (or just the UUID part) by selecting this from an SQL UserDefined Function.
IT Jungle has a nice write-up showing just how to do this:http://www.itjungle.com/fhg/fhg082714-story01.html
So, as you can see, there are options to help you generate a UUID, either from HTTP, Command Line interfacing on your installed machine or through your Database.
