This step is displayed when there is more than one way to relate the table you are adding to the query with the other tables in the query. For example, suppose the table that you have already added to your query contains two columns that each identify an account number (e.g., a payable account and an expense account). Now you want to include the account table in your query. When you add the account table, Liberty Reports needs to know which account number (i.e., which account column) to associate with the rows in the account table.
