Hi,

Below is the mapping for this scenario.
SEQ
||
SRC==>SQ==>EXP==>AGGR==>UNION==>FLT==>TGT
|| ||
EXP==============

1.EXP::SNO(NEXTVALPORT) From Sequence generator
ID <input>
NAME <input>
O_NAME=(IIF(ID=V_ID,V_NAME||' ,'||NAME,NAME)) <Oport>
V_ID=ID <Variablr Port>
V_NAME=NAME <Variable Port>
SAL <I&O>

2.1.AGGR::ID
CNO=COUNT(ID)
2.2.EXP::SNO
ID
O_NAME
SAL

3.UNION the two pipelines(AGGR & EXP 2.2)
SNO
ID
O_NAME
SAL
CNO

4.FLLTER (SNO=CNO/2)
5.TGT

Answer / babu

Sorry to all,

Above answer is have small correction theat is very
difficult to explain here.

i will give one more solution, it is very simple

Mapping:
=======
SEQ
||
SRC=>SQ=>EXP=>AGGR(NOGROUPBY)=>TG1(ID,NAME)
||
EXP=======================FLT==TG2(SAL)

SQ::SELECT A.ID,A.NAME,A.SAL,(SELECT COUNT(ID) FROM TABLE
T) CNO FROM TABLE T

EXP::SNO(NEXTVALPORT) From Sequence generator
ID <input>
NAME <input>
O_NAME=(IIF(ID=V_ID,V_NAME||' ,'||NAME,NAME)) <Oport>
V_ID=ID <Variablr Port>
V_NAME=NAME <Variable Port>
SAL <I&O>
CNO
FLT:: SNO=CNO/2 RETURN SAL
