Stress Strain curve

Hi all.

I am doing simulation with Nonlinear Von Mises material model. Stress Strain curve is found out with tension test experiment. The material is AISI301 3/4 H. As said in solidworks, The first point is yield point and true stress and true strain. But when i run simulation, i got following error.

For Plasticity models, raise: ETAN > Ex/100

I just want to know wether this error is due stress strain curve.
