  Following the linear programming prescription of Ref. \cite{PRA72}, the
$d\otimes d$ Bell diagonal entanglement witnesses are provided. By using
Jamiolkowski isomorphism, it is shown that the corresponding positive maps are
the generalized qudit Choi maps. Also by manipulating particular $d\otimes d$
Bell diagonal separable states and constructing corresponding bound entangled
states, it is shown that thus obtained $d\otimes d$ BDEW's (consequently qudit
Choi maps) are non-decomposable in certain range of their parameters.
