# Mapping

## Process

* Select the tables from the source you want to compare 
* Select the table you want to compare with the source and select the table from the destination 
* Compare by - here, users can select how they want to compare their source and destination tables (through comparing org id, keys, etc.)
* Example - Account.ID=Customer.sfid
* Once tables are mapped, the user can save. Once it is saved, the user will land on the comparison page
* Users can also select the auto-match option to map their tables if they don't want manual configuration
