The Table Settings step allows you to customize various table settings. You can change all or some of the following settings:

• The key that should be used to compare the data between tables. This is useful when a table has no primary key or other unique indexes in SQL Server.
• A where clause that should be used to filter the table data.
• Columns that should be excluded from the comparison.

The following fragment is the xml generated when some tables settings are changed:

<TablePairs>

  <!--**** custom tables ****-->
