Problem Note 13510: Invalid reference value error if REF='level' used for two or more
variables
If, for two or more CLASS variables, you specify the REF= variable
option in the CLASS statement to identify particular reference levels
for the variables, then the following error will appear:
ERROR: Invalid reference value for xxxxxxx.
where xxxxxxx is the name of a CLASS variable. For example, this
statement will generate the error:
class a(ref='1') b(ref='1');
To avoid the problem, remove the REF= options, or use REF=FIRST or LAST
instead of specifying particular values. If you recode the variables or
assign formats so that the intended reference levels have the highest
sorted values, then you can remove the REF= options and get the desired
coding.
A fix for SAS 9.1.3 (9.1 TS1M3) for this issue is available at:
