By default, the

replication

task includes the target prefix SF_. For example, the default flat file name for the Account Salesforce object is

SF_ACCOUNT.CSV

. If you remove the default target prefix and do not specify another prefix, the

replication

task creates a flat file or database table with the same name as the corresponding source object.

You can use target prefixes to prevent overwriting data. For example, you and another user share a database user account. The other user ran a

replication

task on the Contact object from her Salesforce account. Her

replication

task created a database table named Contact in the shared database. You use no target prefix and run a

replication

task on the Contact object from your Salesforce account. The

replication

task overwrites the data in the existing Contact table with your data. If you use the SF_ prefix, the

replication

task creates a table named SF_CONTACT and does not overwrite the existing table named Contact.
