PROC GENMOD for Poisson

Trying to run Possion using genmod, but SAS kept telling me I have a saturated model when I only have one single predictor?

data TWO;

input Predictor_Category Outcome_Count Total;
LTotal = log(Total);
cards;
1   30    351
2   6     39
3   2    80
4   8    71
5   17   169
6   8    118
7   40    281
8   76    281
9   50   318
10   43   586
run;

proc genmod data = TWO order = DATA;
class Predictor_Category;
model Outcome_Count = Predictor_Category / dist=poisson link=log
offset= LTotal type1 type3 ;
run;

You do have a saturated model: you have 10 observations and your model specifies 10 parameter estimates. You'll have to come up with a new vision for analysis.
