CORRECT TEXT
Up to how many custom fields in a standard or custom object can be marked as external id field?
CORRECT TEXT
Lead validation rule (like field Industry must have a value) always triggers when a lead is
converted.
When upserting record using Apex Data Loader for an object that has an external id field, if the
value for this external id field is not provided in the csv file or while mapping fields from the csv file
to the Salesforce object fields, then the upsert will always fail as the external id is a required field.
