Need Help in Infoset Query

Hi friends,

I need to develop a global query for the below requirement;

Requirement:

Find WS AF records with no default methods

select

a.ZZ_NSSHP "Shipment Type"

b.ZZ_FLTORG "flight Origin",

b.ZZ_FLTDEST "flight Destination",

c.ZZ_IATA_NUM "IATA"

from

ZFT_CSISUM_DRVD a,

ZFT_CSIAF_RAW b,

ZFT_CSIAF_DRVD c

where

a.ZZ_TRSQ = b.ZZ_TRSQ

and b.ZZ_TRSQ = c.ZZ_TRSQ

and b.ZZ_LEG = c.ZZ_LEG

and not exists

select *

from

ZFT_SHPTYP_MODEL d

where

d.ZZ_NSSHP = a.ZZ_NSSHP

and d.ZZ_IATA_NUM = c.ZZ_IATA_NUM

and d.ZZ_FLTORG = b.ZZ_FLTORG

and d.ZZ_FLTDEST = b.ZZ_FLTDEST

Detail Description : Basically there are two parts in this;

a) in first part, we need to fetch data from 3 table as below based on the where condition mentioned;

ZFT_CSISUM_DRVD a,

ZFT_CSIAF_RAW b,

ZFT_CSIAF_DRVD c

b) In second part; using the output of first select we need to check data which is not similar ( not exists ) in table ZFT_SHPTYP_MODEL d

Please suggest me how to approach.

Thanks and Regards,

Swapnil
