Answer / kt
We need to use NORMALIZER transformation to convert single
row into multiple rows.
Ex: NAME SALES QUARTERCID KT_NRMSALES_ID
Books 10 1 1
Books 20 2 2
Books 30 3 3
-----etc
TO --> NAME Q1 Q2 Q3
Movies 40 30 70
Books 10 20 30
Furniture 20 10 90
And we need to use aggregator tranformation to do reverse
operation.
In this we have to use any of the aggregate function
SUM/MIN/MAX and then decode to get the particualr quarter
and enable NAME port as group by.
sum(DECODE(QUARTERCID,1,SALES,NULL)) Q1
sum(DECODE(QUARTERCID,1,SALES,NULL)) Q2
sum(DECODE(QUARTERCID,1,SALES,NULL)) Q3

Answer / ani
We cannot use normalizer transformation in this case.
It used for normalizing the records.
Use decode in expression transformation and then aggregator
transformation.

Answer / kalyan
Using Normalizer T/R we can achieve this; Horizantal
Pivoting i.e Coverting Single horizantal record into
Multiple vertical records. Even reverse logic i.e; Vertical
Pivoting also possible using the Normalizer T/R.
Please correct me if I am wrong !!
