I have developed level 2 s function ,which takes one input and give one output,,, The output value is the adiition of input... Y=output,,, x=input,,, My s function does like,,,, y=x+x;,,, it works nicely,,, now i want to develop a logic where the data input x will be saved to workspace every step increment,,, what is the method to do it?

I think it is important to know why you want to save the data at every step.

Are you planning to access it every step while the model is running? If yes, what is the goal? I am asking because most of the time exchanging data with the base workspace is not the best solution.

Are you planning to access it only at the end o the simulation? If yes, then as Kaustubha suggests, use one of the many logging options in Simulink.
