Answer / priya yadav
Hi,
I am not aware at session level but I can tell you the same
at mapping level.
Either Select Distinct in SQ itself or in expression, u can
use a variable v1 to store the business keys of the
records. This will store the business keys(based on which
you have to determine a record as duplicate) of the record
v1= A||B||C
Assign this to another variable v2. This will assign these
business keys to v2.
v2=v1( Now v2 will have value A||B||C)
Set Duplicate Flag as Y if V1= V2 else N.
Now the business keys are stored in v2. Next time the
record will come it will calculate v1 on basis of business
keys, if that record is duplicate v1=v2, and record will be
marked for duplicate. If the record has different business
keys then v1 <> v2, and the record will not be marked as
dupliacte.
Hope it helps.
Thankyou!!
