deleting tasks

[Tomcat]

I am importing data from Access to Project with outline levels for the
different tasks. Because of the generalities of my Access database, I
sometimes will have a summary task, outline level 1, with no subtasks,
outline level two. I know I could go in and delete these by hand but my file
is around 10,000 tasks and this would take too long. Is there away I can
automate this deletion process. For example, press a button that would
delete all tasks with outline level one without summary tasks underneath
them. I don't want to filter a view because the "summary tasks" with no
subtasks still affect my overall project percent complete and so on. Thanks
for your help.

If the tasks are truly unnecessary then filter before you import.
It is fairly trivial to write a macro to delete these tasks.

Sub tomcat()
Dim t As Task
For Each t In ActiveProject.Tasks
If t.OutlineLevel = 1 And t.OutlineChildren.Count = 0 Then
t.Delete
End If
Next t
End Sub

You can assign the macro to a toolbar button.
