Eliminating of duplicate records without using dynamic lookups

Answer Posted / vikram

To eliminate duplicate we use Source,Source qualifier,Look
up T/N, router T/N AND Target.. In This Case we use dynamic
cache


BUT USE
example emp table consist of i.d salary,name dept no.
eliminating the duplicates of dept no.

Source,Source Qualifier,Sorter T/N,Expression T/N,Router T/N
And split target in to two as duplicates and distinct
we have to create 3attributes in expression T/N AS
V_pre_deptno v_flag 0_flag
give condition as v_pre_dept no = dept no
v_flag= IFF(dept no = v_pre_deptno,1,0)
