How to pass first party cookie data layer value in UDO.
eg: UDO name - "user_id"
Cookie - _ptmz (added from web campaingin tool).
Now i want to pass "_ptmz" value into user_id udo as this mapped with GUA UID varibale. should i change scope of user_id from UDO to Cookie in Tealium?

Hello @ani2012. To make sure I'm understanding correctly:
1) You have user_id mapped into GUA's UID variable
2) You want to also have the value from the cookie "_ptmz" mapped into the UID variable.
If that's correct, then you shouldn't need to alter the user_id at all. The beauty about mappings is that you can map multiple variables to a tag and it will accept the last one populated with a value. So, assuming user_id is a udo variable and _ptmz is a cooke variable (and both created in the data layer tab) then you could do a mapping like so in the GUA tag:
Then, if one or the other variable is populated, then the uid will get populated. If both variables are populated, then the _ptmz would take priority since it is lower on the list.
