abstract = {Let    D be a division ring such that either char   (  D  )  ≠  2  ,  3 or    D is not a field and char   (  D  )  ≠  2. Let    R  =      M    n    (  D  ) be the matrix ring over    D, where    n  &gt;  1. Let    m  ,  k be fixed invertible elements in    R. The main purpose of the paper is to give a description of a bijective additive map    f:    R  →  R, satisfying the identity    f  (  x  )  f  (  y  )  =  m for every    x  ,  y  ∈  R with    x  y  =  k, which gives a correct version of a result due to Catalano et al. in 2019.}
