Abstract: An electronic maintenance support work station employs a text screen and graphics screen on which text records and part graphics are displayed. The user can sequence through various levels of hierarchy of the product structure as a search is made for a needed part. An item activated on the text screen is automatically targeted on the graphics screen. Part detail information is presented to facilitate decision making when an order point in the search is reached. Direct part or stock number entries can also be entered if the user desires to bypass a search.
