If you have previously defined CLASS1 in a LIBNAME statement, then you want

group by mismatches1.product_id

or, since there is only one data set mentioned in the FROM clause, you could also use

group by product_id

So you have not defined CLASS1 in a LIBNAME statement? There is no LIBNAME in your log.

When you show us the log, you need to click on the {i} and paste the log into that window. Do not show us logs any other way.

Except in the FROM clause a reference like ABC.PDQ means that ABC is a data set reference or alias and PDQ is the variable named PDQ in the data set ABC.

So your statement

76 group by class1.product_id

is attempting to reference a dataset named class1 that has not been defined. If you want to use the variable Product_id that comes from the data set class1.mismatches1 then only use

group by product_id

You can create an alias to data set by

from library.dataset <as> abc

the as is optional but I normally use it to keep the intent clearer.

Then to reference a variable in the dataset library.dataset you use abc.varname.

This is mostly import when two or more data sets are used in a single proc sql statement and especially when two or more sets have a same named variable to reference which data set you want to contribute the value.
