Can you please define what a UUID is please.
Or....that is to say....no matter what you consider a UUID, if a GUID doesn't work for you, you will need to work with an external system to generate the UUID, and then determine a method for your Remedy system to get that ID from that system after it's generated
what is the expected sample data value for UUID? Are you trying to pass this using web services?
Yes we need to pass UUID to webservice and i completed this requirement using java integration.
There are a number of methods, I suppose depending on how you want to get the value.
I'd suggest java or jsp should do the trick ... String key = UUID.randomUUID().toString();
You could also create a database function to return the uuid.
Can you explain how you achieved this please.
