Incompatible Field Mapping

When you upload a .csv file and map its headers to Big Table fields, some fields may have incompatible data types. For example, "Email" is mapped with the "Number" field, or "Date" is mapped with the "Email" field.

When this happens, clicking Save & Create BT Records does not create the Big Table record and an error file is attached under Files. The error message is displayed as something like this: Data type incompatible - CSV column "Email" mapped to BT Field "Number" :: Invalid decimal: willsingh@mailinator.com
