External ID

 

It is a custom field that has the “External ID” attribute checked meaning that it contains unique record identifiers from a system outside of Salesforce.

When we select this option the import wizard will detect existing records in Salesforce that have the same External Identification.

This operation is case-insensitive but if the custom field has separate “Unique” attribute then the case sensitive option for that field is selected that means Uppercase and Lowercase letters will not be considered identical.

An object can have at most 7 external ids’ fields. The field type should be any one of auto-number, email, number or text.

Custom fields marked as unique also count against an object’s limit of 7 external ids’ fields.

 

 

Let’s move forward to Record ID.
