Event elements that refer to specific occurrences should be defined in the Dictionary, so that information about specific events can be stored and updated centrally in a dictionary entry. Information about when the event is used in processes can also be defined here.
In the Dictionary, terms can be centrally documented and renamed. The Dictionary ensures that all instances of the same event in process models of the same workspace are updated simultaneously. You can choose a dictionary entry while naming an event if an entry for it already exists in the Dictionary. Otherwise the event can be added to the Dictionary by clicking the Dictionary icon at the bottom left of an element.
To fix this error, add a dictionary entry. To choose another entry or if the required entry is not displayed, click the dictionary icon at the corresponding element.
