Consulta SAP HANA
 

Tengo un problema en SAP HANA realice un Query
SELECT T0."DocNum", T0."DocStatus", T0."DocDate", T0."DocDueDate", T0."CardCode",T3."DocDate", T0."CardName", T0."PaidToDate", T1."SlpName", T2."ItemCode", T2."Dscription", T2."LineTotal" FROM OINV T0 INNER JOIN OSLP T1 ON T0."SlpCode" = T1."SlpCode" INNER JOIN INV1 T2 ON T0."DocEntry" = T2."DocEntry", ORCT T3 WHERE T0."DocStatus" =[%0] AND T3."DocDate" >=[%1] AND T3."DocDate" <=[%2] GROUP BY T2."ItemCode", T0."DocNum", T0."DocStatus", T0."DocDate",T3."DocDate", T0."DocDueDate", T0."CardCode", T0."CardName", T0."PaidToDate", T1."SlpName", T2."Dscription", T2."LineTotal"

Y cuando lo despliego en pantalla el T0."DocNum" me sale repetido en mas de un cliente , alguien me puede indicar que hice mal por favor

Mil Gracias
