Hey SMN,

Sorry to hear that you were confused about Exercise 4. Let me help you by clarifying the problem.

In the dataset of Exercise 4, look at the rows of Order ID A001, A002, and A003. These orders are placed at the same Date & Time by the same Customer. Therefore, only the row of Order ID A001 is considered a New Order. Similarly, rows of Order ID A015, A016, A017, A018, and? A019 are placed on the same Date & Time by the same Customer. Therefore, only the row of Order ID A015 is considered a New Order.

In Exercise, 4 your primary task is to identify these New Orders. While this can be achieved with a simple formula, an additional requirement of this Exercise is using structured references with Excel tables.

Therefore, you have to convert the data range into a table first. And then apply formulas to identify new orders.

The primary concept behind solving this Exercise is to compare the Date Time and Customer values of each row with the Date Time and Customer values of the previous row. If any match is not found, then the current row is considered a New Order.

I hope this explanation will help you understand the exercise problem and its solution. Let us know your feedback.
