Abstract: Let f be a conjugate $\lambda$-normally embedded $\pi$-soluble Fitting functor and let $f_*$ be the smallest element of the Lockett section of f with respect to strong containment. A generalized version of an open question of Beidleman-Brewster-Hauck is to give a description of $f_*$. In this paper such a description is presented.

Keywords: Lockett's operation, Lockett section, Fitting $\mathfrak{X}$-functor.
