When you create a synchronous or asynchronous message,
a behavior specification is created automatically. You can delete
a behavior specification from the model without deleting the message.
You can also create an asynchronous message without a behavior specification
by selecting Asynchronous Signal Message (No BES) from
the Palette.
Before you begin
You must have a sequence diagram open that contains a message
About this task
To delete a behavior execution specification from a message,
right-click the behavior execution specification in the diagram; then
click Delete from Model.
What to do next
The behavior execution specification is removed from the
model but the message remains.
Note: To change the default preferences
for behavior execution specifications: Click and set the preferences and click OK.
