          Bug - A problem that impairs or prevents the functions of the product. RHDM-1709 for-each for the property of fact causes compilation error in executable models.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
