The preview during mapping will only show you the first 3 orders in the file.

If the header does not extend to the last sku in the biggest order then additional mapping will be required.

If the sku's are not mapped then they will drop off the order.
- Paying attention to the percentage of rows with data for that column to confirm all columns are mapped correctly can ensure nothing is dropped.

The mapping process will only ask to map rows that contain data.

To map unknown headers use the drop down and select the correct option.
