SAS Question on Panel Data

I can get the program to work by industry (please see error message below). What is being incorrectly? I am not sure why/ el Thanks

790 PROC PANEL DATA=SASUSER.CSR3 plot=none;
791 WHERE TYPE = 0;
792 MODEL ISCORE = CSR_Spending ROE ROA ROS OPERATING_INCOME MAN FARM MINE UTIL CON RETAIL
792! TRANS INFORM FIN ADMIN EDSOC ENTER SIZE/ RANTWO VCOMP=WK;
793 ID SYMBOL YEAR;
794 RUN;

NOTE: The transformed regression does not have full rank. User should be aware of possible
multicollinearity and/or estimability problems before using RanTwo method results.
WARNING: Hausman statistic cannot be calculated because different variables were dropped in the
random effects model than in the fixed effects model.
NOTE: PROCEDURE PANEL used (Total process time):
real time 0.03 seconds
cpu time 0.01 seconds
