I'm making a program and I need to reduce the size of the query to the important data inside of one subform. In other words: In the form i put the code of the client and in the subform I put the articles. Each article have one price from other table. I want that when I put the code of the client I open the price table in a snapshot only with the prices for that client. Like this after when I put the code of the article I only need to look in few regists. CAN SOMEBODY HELP ME?
