In Power Query, which built-in function can be used to create a status field for orders over 30 days?

Using a conditional column in Power Query is an effective way to create a status field for orders over 30 days, as it allows for straightforward logical evaluations based on existing data in your dataset. By setting conditions, such as checking the order date against the current date and calculating the difference in days, you can categorize orders into different statuses, such as "Overdue" or "On Time."

The approach enables users to easily define rules for different scenarios using simple if-then logic, which is particularly useful for creating classifications or statuses based on numerical or date values. This functionality is intuitive and tailored to solving this type of problem without requiring extensive coding or complex transformations.

Other options, such as creating a custom function, would involve additional coding and complexity that aren’t necessary for this specific task since Power Query’s conditional column feature is designed for simple logic operations. Changing data types is useful for ensuring the correct format of data but does not provide the capability to create logic-based evaluations for a status. Merging queries is a different operation altogether, primarily focused on combining datasets rather than assessing individual records.
