asi como lo quieres no va a quedar quedaria de este modo:
Código SQL:
Ver originalSELECT cardcode,SUM([total en bs], SUM (total) FROM(
SELECT T0.DocNum,T0.[CardCode], T0.[DocTotal] AS 'TOTAL EN BS' ,SUM(T1.[Quantity]) AS 'TOTAL' FROM ORPD T0 INNER JOIN RPD1 T1 ON T0.DocEntry = T1.DocEntry WHERE T0.[DocDate] >='20130101' AND T0.[DocDate] <= '20130125'
GROUP BY T0.DocNum,T0.[CardCode],T0.[DocTotal]
ORDER BY T0.[CardCode]
) t1 GROUP BY cardcode
saludos!
