Let N be a 3-prime near-ring with a nonzero generalized semiderivation F associated with a semiderivation d and an automorphism g associated with d and U be a nonzero semigroup ideal of N: In this paper, it is shown that N is commutative ring, if any one of the following conditions are satisfied: (i) F(U) ⊆ Z; (ii) F([u; v]) = 0; (iii) F([u; v]) = ±[u; v]; (iv) F([u; v]) = [F(u); v]; (v) [F(u); v] ∊ Z; for all u; v ∊ U:.
