What are you trying to do? GROUP BY is designed for aggregating results, that is, for combining data from multiple records into a single record. It's always used in conjunction with the aggregate functions: COUNT(), SUM(), AVG(), MIN() and MAX().

I'm wondering if you really want ORDER BY in your query to organize the results in order by the value of cPues.

Also, while you're there, get rid of the macro operator and use a name expression instead: FROM (ivaventa)
