Starting from the transformation properties of constrained system which is a general transformation results of action and constrained equations, we obtain generalized killing's equations of constrained system. The transformation generated by the solution of generalized killing's equations, may yield classical Noether's conservation quantities. We have considered the time-space and internal transformation of continuous constrained system which leave constrained equations invariant and give a necessary and sufficient condition that transformations may yield conservation current. The application to incompressible continuous media are presented. The application to generalized and classical mechanics are discussed and some illustrations for the solution of generalized killing's equations are also given. The Poincare's invariant is generalized to constrained generalized mechanical system.
