Record Updating with AppExchange Data Loader

D.

The AppExchange Data Loader is a powerful tool that allows administrators to import, export, and update large amounts of data in Salesforce. When updating records using the Data Loader, there are several fields that can be used to identify the records that need to be updated.

Of the options provided in the question, all except for "Record Number" can be used to update records using the AppExchange Data Loader. Here's a closer look at each of these fields:

A. External Id: An external ID is a custom field that is marked as unique and can be used to identify records that may not have a unique Salesforce ID. External IDs can be used to update records even if the Salesforce record ID is unknown.

B. Parent External Id: This field is used to specify the external ID of a related record. For example, if you are updating a contact record and need to specify the account that the contact is associated with, you can use the Parent External ID to identify the account.

C. Record Id: The Salesforce record ID is a unique identifier for each record in the system. This ID can be used to update records using the AppExchange Data Loader.

D. Record Number: This field is not a valid field when updating records in Salesforce. It is not a standard Salesforce field, and cannot be used to identify or update records using the AppExchange Data Loader.

In summary, when updating records using the AppExchange Data Loader, you can use the External Id, Parent External Id, or Record Id fields to identify the records that need to be updated. The Record Number field is not a valid field and cannot be used for this purpose.
