Have a GUID field auto populate with an Attribute rule

[CHedger1227]

Hello,

I am trying to create an attribute rule that will auto populate a GUID field type. I know how to do it with the field calculator but I am unsure of an attribute rule that can do this. I want it so when a new piece of data is put in it populates the GUID field with GUID data without me having to do anything.

Is this possible?

There is a GUID Arcade function that should do the trick.

So I think the below will work if that is the format you are looking for.

return GUID('digits')

That did not seem to work for me. all i had to do was paste the code as is correct? because that gave me an error saying invalid expression.

Thank you @KimGarbade for the response 

It gives an error that says Invalid Expression. I do not believe that works for me. was it able to work for you Kim?

Sorry about that.  Try just  'Return guid()' (without the 'digits').  This worked for me (I just tested it).

return guid()
