I have a small Sample (with 30 points/observations) as variable "Sample" inside a Data Set named 'Data'.
I would like to know how to test if the this sample has a Normal Distribution.

And if the sample size is large (N>100) the tests are over-powered, where even small deviations can lead to a significant result.
Follow Doc's advice and look at the plots, especially the pp and qq plots.

This should get you started:
ods graphics on;
PROC UNIVARIATE DATA=sashelp.iris(where=(Species="Virginica"));
histogram SepalLength / Normal;
qqplot SepalLength / Normal;
