I have two applications, Customer.db and Sales.db.  In Sales.db there are XLU commands which retrieve data from data\Customer.db.  After I merge the Customer.db into Sales.db, don't I want those lookup commands to begin retrieving the data from the Customer database in the Sales application (and no longer from data\Customer.db) because additions and updates to the merged Customer database in the Sales application don't show up in data\Customer.db?  How do I structure the XLU command to get the data from a database within the same application?  I've tried using @fn but must be doing something wrong.  Thanks.
