In Aras Innovator, we could execute command "Where Used" to check where the item is used like below picture. And for programming, AML provides an action "getItemWhereUsed" to do this. <AML> <Item type=" Item Type " id=" Item Id " action="getItemWhereUsed" /> </AML> Results will be contained in tag "relatedItems", just use XPath to retrieve.
Programming notes from a non-expert guy who keeps learning in various applications.
