For the query items Object and Connection you can define whether the query will relate to object definitions or object occurrences. Depending on the selected level, the query returns different results.
Depending on connections, conditions, and the related items, you cannot always change the evaluation level. The Occurrence level and
Definition level buttons are active in the Start tab bar only if switching the level is possible for the selected items.
Even if your selection is not complete, for example, because the level would have to be switched for related items, you can change the level. In this case, a message is generated and the required query items are selected automatically. Clicking Yes in the dialog assigns the selected level for all selected items.
You can switch the level for individual query items by double clicking the relevant or
icon in the item.
Prerequisites for switching to occurrence level
Definition level is automatically assigned to the start item. It cannot be changed. Only definition level can be assigned to all successors of the start item except Model.
Prerequisites for switching to definition level
Definition level can be selected for query items only if definition level is also selected for successors.
