Crossover Domains explained
A crossover domain in Maximo 7 is a value list that copies not only the selected value, but also related data to the record you opened the value list from. An easy example is the Asset field on a work order. When you select an asset, Maximo also copies the priority from the asset to the Priority field on the work order. This happens because there is a crossover domain for this. Take a look at it: in the application Domains, search for ASSET2WO.
