How to populate Google Analytics Premium UserID for Rollup Properties

[Michael_Kim_shc]

How can I set/send the UserID for cross-device reporting in the Google Analytics Tag?

I've not seen somewhere to put it yet...

Thx!

Hi @Michael_Kim_shc,

It seems like mapping to "UID" in the Google Universal Analytics tag will set the User ID.  You can find this under the Standard tab in mapping.
