I am using curve fitting toolbox for Z=F(x,y)
I am getting results in this below form. Where I can do the setting where I can define max allowed error 0.09 .i.e max I put x & y backin generated equation max devaition I should get from Z is +-0.09 only. This is max/min error in "Z" where I can define that.
Goodness of fit:
SSE: 1.08e+07
R-square: 0.994
Adjusted R-square: 0.994
RMSE: 16.8

Will polynomial fit or any other fit equation is formed, it will give a equation, in which when x and y are fitted, will return Zeq.
I consider error = Zer-Zoriginal
the absolute error should not increase +-0.09999.
This is what I am aksing, is there any setting to do that?

As John, says, "No".
It isn't a necessarily fulfillable condition for a specific model (order of polynomial, say).
You could try successive orders of a polynomial until met the condition altho would be easily prone to overfitting that way.
