Hi All,

I would like to use xtk.session.Write method, but checking for lower case of _key parameter with lower case of source field like we can do in the Update data activity:

 

collection.appendChild(<{"mycusTable"} Status={1} StatusChangeDate={date} _key="@ID" Id={id} xtkschema={"mycusTable"} />);

 

something like this :

_key=lower("@Id")

 

But what is a proper syntax for converting _key value to lowercase?

 

 

Thank you
