On the "Data Schema Editor OSM Tab", you can define behaviors for data, which enable you to extend the functionality and appearance of order data. Each behavior type performs an action; for example, calculating or validating data or displaying fields in read-only mode.
To define behaviors for data:
Double-click an element from the Data Element view.
The details for the selected element are displayed in the Data Schema editor.
Click the OSM tab.
Select the data element for which you will define the behavior.
The Add Behavior dialog box is displayed.
In the Behaviors area, right-click and select Add Behavior, and then select the behavior type.
The newly created behavior appears in the Behaviors list.
Select the behavior from the list and click Properties.
The Properties tab opens with the set of properties that you can define for this behavior type.
See "Working with Behaviors" for information on how to set behavior properties.
