Best Practices

DeleteWorkDefinitionSegment (IProductionModel)

Deletes the selected work definition segment.

Note: If the selected work definition segment is a parent to one or more child work definition segments, deleting it removes only the association with the child segments; that is, the child work definition segments are not deleted.

Inputs	Data Type	Description
Work Definition Segment	DirectoryResource	Specifies the work definition segment to delete.
