Simple Cert will require that you provide a mapping designation for every Data Field that you have listed on a Certificate Template. If your certificate has mapping fields that you no longer intend to use, simply edit your CertificateTemplate to remove those unwanted Data Fields. If your upload list has more fields than you intend to use as part of your certificate, you can either manually delete those unwanted fields before you upload your list, or just not map those unwanted fields to a specific Data Field. Any fields that are not mapped to a Data Field on a certificate will be disregarded by SimpleCert®.
