We holographically study supersymmetric deformations of 
and 
superconformal field theories in three dimensions using four-dimensional 
gauged supergravity coupled to three-vector multiplets with non-semisimple 
gauge group. This gauged supergravity can be obtained from a truncation of 11-dimensional supergravity on a tri-Sasakian manifold and admits both 
supersymmetric and stable non-supersymmetric 
critical points. We analyze the BPS equations for SO(3) singlet scalars in detail and study possible supersymmetric solutions. A number of RG flows to non-conformal field theories and half-supersymmetric domain walls are found, and many of them can be given analytically. Apart from these “flat” domain walls, we also consider 
-sliced domain wall solutions describing two-dimensional conformal defects with 
supersymmetry within the dual field theory while this type of solutions does not exist in the case.
