2 ways to do it
1- input -> Transformer -> RDP-> output
Sort the input on location, company
do a comparison in Stage Variable with prev record and keep incrementing a counter
pass it via Remove duplicate stage to retain unique records
2- input-> copy-> agrregator-> lookup-> RDP -> output
do the same as above using agg and lookup stage

Answer / sreepathi

Hi

Use stage variables in Transformer stage i.e IF THEN ELSE
IF ..condition comparing companies and use COUNT() function
in transformer for which field u want count

Answer / saibal kumar giri

Follow below steps-----
1.Read the data with sequential file or connector stage.
2.Use copy stage to streamline the data into two links
a.One data goes to lookup stage.
b.Second stream goes to aggregator stage.
3.In aggregator stage do a count(LOCATION) group by COMPANY.
you will be having data O/P from AGG as below
COMPANY COUNT
TCS 2
HCL 3
IBM 3
Use this output data as the reference link of lookup
stage.Where you have original source as master data.
4.Do a Inner join by lookup stage.
after lookup you will have data like
COMPANY:HCL LOCATION:HYD COUNT:3
COMPANY:HCL LOCATION:CHE COUNT:3
COMPANY:HCL LOCATION:BAN COUNT:3
COMPANY:IBM LOCATION:CHE COUNT:3
COMPANY:IBM LOCATION:BAN COUNT:3
COMPANY:IBM LOCATION:HYD COUNT:3
COMPANY:TCS LOCATION:BAN COUNT:2
COMPANY:TCS LOCATION:CHE COUNT:2
5.Then use a transformer stage along with stage variables
as below
SV1->link1.COMPANY
SV3-> if SV1=SV2 then SET NULL() else link1.COMPANY
SV2->SV1
Similarly for count also
Cheers!!!!!
