Input Seq File:-

NAME,LOC
Ram,hyd
Ram,ban
Raj,chn
Raj,Pun
Sam,del

seq---Trans---Rem Dups----> Dataset


TRANSFORMER:
------------
STEP1:

Create 3 stage variables like s1,s2,s3

DSLink3.NAME --->s1

If s1<>s3 then DSLink3.LOC else s2:DSLink3.LOC --->s2

s1--->s3

STEP2:

Derivations Column bane

s2------------> LOC


Remove duplicate stage:
-----------------------

Key == NAME

Duplicate To Retain = Last


Output Dataset result:-

NAME LOC
Ram Hyd ban
Raj chn pun
sam del

On which Dimension Table you implemented SCD Type in your Project

create a job that splits the data in the Jobs.txt file into four output files. You will direct the data to the different output files using constraints. • Job name: JobLevels • Source file: Jobs.txt • Target file 1: LowLevelJobs.txt − min_lvl between 0 and 25 inclusive. − Same column types and headings as Jobs.txt. − Include column names in the first line of the output file. − Job description column should be preceded by the string “Job Title:” and embedded within square brackets. For example, if the job description is “Designer”, the derived value is: “Job Title: [Designer]”. • Target file 2: MidLevelJobs.txt − min_lvl between 26 and 100 inclusive. − Same format and derivations as Target file 1. • Target file 3: HighLevelJobs.txt − min_lvl between 101 and 500 inclusive. − Same format and derivations as Target file 1. • Rejects file: JobRejects.txt − min_lvl is out of range, i.e., below 0 or above 500. − This file has only two columns: job_id and reject_desc. − reject_desc is a variable-length text field, maximum length 100. It should contain a string of the form: “Level out of range: ”, where is the value in the min_lvl field. My Question is how do you write the stage variable for reject rows.
