Script SQL: Distinct script between Rich Client and IDT 4.1 SP5

Hi Experts,

I am working with IDT linked to Oracle 11. I have created a query in IDT 4.1 SP5 and the script generated is the next:

SELECT

ZG.COD_ELEMENTO,

ZG.DES_ELEMENTO,

DELEG.COD_ELEMENTO,

DELEG.DES_ELEMENTO,

DIV_CONF.COD_DIVISION,

  DIV_CONF.DES_DIVISION,

  sum(NVL(CONF.EMPLEADOS_CONFLICTO,0))

FROM

VIGIA.VIPR_TELEMENTO  ZG,

VIGIA.VIPR_TELEMENTO DELEG,

VIGIA.VIPR_TDIVISION  DIV_CONF,

VIGIA.VIPR_VEMPLEADOS_CONFLICTO CONF,

VIGIA.VIPR_TNIVEL NP,

VIGIA.VIPR_TELEMENTO_REL REL

WHERE

  ( REL.OID_ELEMENTO_SUPERIOR=ZG.OID_ELEMENTO )

  AND  ( REL.OID_ELEMENTO =DELEG.OID_ELEMENTO )

  AND  ( DELEG.OID_NIVEL =NP.OID_NIVEL )

  AND  ( CONF.OID_ELEMENTO(+)=DELEG.OID_ELEMENTO )

  AND  ( CONF.OID_DIVISION=DIV_CONF.OID_DIVISION(+) )

  AND 

  (

   ( NP.NEL_NIVEL = 3  )

   AND

DIV_CONF.COD_DIVISION  IN  ( '12','14','16','19'  )

  )

GROUP BY

ZG.COD_ELEMENTO,

ZG.DES_ELEMENTO,

DELEG.COD_ELEMENTO,

  DELEG.DES_ELEMENTO,

DIV_CONF.COD_DIVISION,

DIV_CONF.DES_DIVISION

I have a report in Web Intelligence. A query with the same objects and the script sql generated is the next:

(

SELECT

  1 AS GID,

  ZG.COD_ELEMENTO,

  ZG.DES_ELEMENTO,

  DELEG.COD_ELEMENTO,

I don’t understand why Webi generates other script! I have performance problems with this type of sql generated by Webi

Sorry for my English.

Thanks in advance for ours answer.
