Answer / narender.vankuri
Hi am Narender Reddy take an example:Dept table
Source->source Qualifier->After this we take one Aggregator and one Expression -> and both of this connected to Joiner -> this connect to Router->Here we take one Sequence generator and connect to Router-> this router connect to Targets
Here we see conditions:
1) In Aggregator create Cnt Port and(No input ,only output) There expression Condition(COUNT(DeptNo)
In this create One extra port Decimal express:1(no input,only output)
Disable Groupby
2) In Expression create one extra port decimal expression:1
this 2 transformations(Aggregator,Expression) are connected to Joiner
3)In Joiner Enable SorterInput,Condition And connect to Router Input.
4)Take one Sequence Generator and connect to Router Nextval
5)In Router Group1:Nextval<=(Cnt/2)
6)In Router Group2:Nextval>(Cnt/2)
7)Now connected to Traget1,Target2.
ThankYou
