It should still take the value from the curve. If you want to be certain, run a test with a deliberately different value in the table and compare results.
For reference, see the SOLIDWORKS Simulation Help > Simulation Materials > Defining Stress-Strain Curves which states:
"When you define a stress-strain curve, the first point on the curve should be the yield point of the material. Material properties like elastic modulus, Yield strength, etc will be taken from the stress-strain curve when it is available and not from the material properties table in the Material dialog box. Only the Poisson's ratio (NUXY) will be taken from the table."
Please refer to KB solution S-058935 for additional information.
But for Plasticity model the strain should be plastic strain. So that mean At yield stress the strain value is zero. How can we used that in Solidworks ?
It sounds like your curve shows stress vs. the plastic component of strain. For elasto-plastic material models, SOLIDWORKS Simulation expects stress vs. (elastic + plastic) components of strain as the input. So you will need to convert your curve.
I recommend the following KB solutions which provide additional insight:
