Use this step of the wizard to identify the primary table or view for your query. If you plan to have your query return information from more than one table or view, you must still select one table or view that will be considered the primary table. This would be the table or view for which every row in the table (meeting your criteria) should be represented (either in detail or summary form). Often, this will be the table or view that contains the most amount of detail.
For example, if creating a query from purchase order information, you might find that the data you want is located in a purchase order header table as well as a purchase order detail table (representing the line items of your purchase orders). The more detailed table would therefore be the purchase order detail table and that will often be the best candidate for the primary table that you must identify in this step.
