We study the implications of R-parity-violating (Rp) Minimal Supersymmetric Standard Model (MSSM) in lepton polarization asymmetry (ALP) in B l+l- decays. The analysis shows that the ALP is significant only in a certain phenomenological parametric region of Yukawa coupling products and branching fraction. The analysis further shows how arising from type-II Higgs Doublet Model (2HDM) is constrained in the presence of Rp Yukawa interactions.
