For that you have to assume the same for 'm' as well -

sympref('HeavisideAtOrigin', 1);

syms m n positive integer

s(n) = symsum(heaviside(m), m, [0, n])

s(n) =

Thanks a lot

% clear

sympref('HeavisideAtOrigin', 1);

syms n positive integer

syms m

s(n) = symsum(heaviside(m), m, [0, n])

s(n) =

assume(m,"positive")

s(n) = symsum(heaviside(m), m, [0, n])

s(n) =
