Daniel,

Try

SELECT dpvc.cEDP, dpvc.nPVC, dsvc.nSVC 
	FROM (
			SELECT cEDP, nPVC FROM mytable  mt1 
		 		WHERE dUpdatedOn = (SELECT MAX(dUpdatedOn) FROM mytable WHERE cEDP = mt1.cEDP AND nPVC <> 0 )
		) dpvc
	JOIN (
			SELECT cEDP, nSVC FROM mytable  mt1 
				WHERE dUpdatedOn = (SELECT MAX(dUpdatedOn) FROM mytable WHERE cEDP = mt1.cEDP AND nSVC <> 0 )	
		) dsvc ON dsvc.cEDP = dpvc.cEDP

>I would like to group by the cEDP and when duplicate EDP exists use max(dUpdatedOn) to get the nPVC and nSVC values except for when nPVC or nSVC value is 0.00. Based on the above data I would like the following results:
