It is an ID that we specify for our identification while
using a job in multiple instances. One unique ID for each
instance of the job. When we enable to run a job in
multiple instances, DS engine would throw a window where in
we need to specify the invocation ID for that instance.
When we check the log in director, we can identify the job
by its name followed by its invocation ID.

1)s.key generate 1 to 700 records today. tomorrow another 400 will updated how to update the records using s.key generator? 2)source is like :-- DB --> T/F stage1 --> seq1file T/f 1 is linking with T/F2 ---> seq 2 how to load the data? in source i given some conditions those r going in seq1. The another data will going to seq2 how to do this ?

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.
