If there are columns in the SELECT clause that are not aggregates you
must have a GROUP BY  clause and all of the non-aggregate columns must
be included in the GROUP BY clause.

select id, max(CRDRPT_RNW) from mempay2
where id = 21
GROUP BY ID

In this case all of the columns in the SELECT clause are aggregates so
the GROUP BY clause is not required.
