While importing, it says a mandatory column is missing. What should I do?

• After selecting your file to import, you will be redirected to a page called Map Fields.
• On this page, you have to map the columns in your file with the fields of Zoho Books. Certain fields are mandatory in Zoho Books and will be highlighted in red with an asterisk (*).
• Ensure that the fields in Zoho Books marked as mandatory are mapped with the columns in your file accordingly.
