I'd like to carry out a statistical significance test to see if there's a difference in proportions from 2 different samples.
Let say I have 3 different ethnic groups namely Caucasian, Asian and Others in sample A and sample B.
How do I test if proportion of Caucasian in sample A is statistically different from the proportion of Caucasian in sample B? Same to that of Asian and Others.
Your help is greatly appreciated

Could use PROC FREQ and the CHISQ?
Chi-sq will tell you that at least two of the proportions differ.
PS:you may need to re-arrange your data something like:
input sample $ ethnicity $;
proc freq data = have;
