5. Import the data: Click on “Load” to import the data into a new table.
Method 4: Create a Reference Table
A reference table is a read-only copy of an existing table that allows you to access the data without modifying the original table.

“`
Copy of Table =
VAR OriginalTable =
RETURN OriginalTable
“`
2. Copy the data: Right-click on the newly created measure and select “Copy.”
3. Create a new table: Paste the copied data into a new table.
