This is done by using the Change_Capture_Stage.

In the CDS stage: specify the change key's--> cid and
change_values as cname,add and phone etc

CDC stage triggers the Change_code as 3 if there is any
changes in the cname or add or phone no for the existing cid.

Ex: cid,cname,add,phone,email
1,'vin','bang','08979','vin@Gmail.com'

REf:
cid,cname,add,phone,email
1,'vin','HYD','08979','vin@Gmail.com'

O/P: cid,cname,add,phone,email,Change_code
1,'vin','HYD','08979','vin@Gmail.com',3

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.
