Motion of a rigid body constrained

  Hello everyone.
  I'm simulating two objects to be coupled. One is a rigid body while the second one is a bag. I need to move the rigid body to a defined position. In the ls dyna version 971 I impose the rigid constrains and to move the object I impose a displacement. Everything works well. In the version R11, when I do the same thing, a WARNING 30120 occurs (The y-translational degree of freedom rigid body XX is restrained but has a velocity boundary condition applied . The velocity will be set to zero.
  How can I apply the motion on a rigid, constrained body on the new version of LS DYNA?
  
  Thanks

  Are you implying both the BC on to same body?, How about CNRB and apply prescribe motion rigid card? have you tried that?
