Hi,
Those lines are a predefined function executing in your transform.
They are in place to prevent unintentional overwrite of variable values, in case there exists the same variable name elsewhere in the system.
By wrapping all executing code inside a function, like this one, you can safely have the same variable names in many scripts without them interfering with each other.
I'm not sure what the highlighted parts in the script actually mean, but I would say it's safe to let them be as is.
To import data according to your requirements, I would set Coalesce on field_a and then the import should work fine with your script above (or you could add the logic as a onBefore Transform Map script (image below) if you prefer, it will have the same result).

Hi @Renee-17 ,
To start, let's delve into the concept of self-executing functions in JavaScript. In such functions, parameter passing occurs within the lower section of the function body.
Consider the following script:
(function(param1, param2, param3) {
if(param3){//True
gs.log(param1);//pen
gs.log(param2);//pencile
}
})("pen","pencile",true);
Moving on to the script in question, it sets the variable isUpdate to true based on the action parameter. However, whether the script executes isn't solely determined by whether it's an update operation; rather, it hinges on how the script is defined within the function.
Please mark my answer correct and helpful if this works for you
Thanks and Regards
Sarthak
