Question:Problems with ztrans and Heaviside

When I try and to z transformations and inverse z transformations using the Heaviside function as follows Maple doesn't seem to be able to handle it; does anyone have suggestions?

 

ztrans(Heaviside(n-No),n,z) assuming No:posint


would expect z^(-No) * z/(z-1) but no results, does work if No replaced by a specific integer

Similarly, ztrans(x(n-No),n,z) assuming No:posint  acts the same.
