External ID vs Custom ID field

edited Jan 8, 2020 3:39AM in SuiteCloud / Customization 3 comments

Hi everyone,

We're in the midst of importing our Contacts/Customers into NS, and are curious about the External ID field.  Our current customers/contacts have a unique ID, and we created a custom field to enter this data.  However, we've noticed the External ID field and are wondering if it's better if we use that existing field?  Are there any special properties about this External ID field?  I know you can match up relationships between Customers/Contacts while CSV importing, but can you use the External ID field to help with the matching/mapping?

Thanks,
Jordan

Howdy, Stranger!
