SeqFile1----->|
.................|ChangeCapture--->Transformer--->TGT
SeqFile2----->|

SeqFile1 & SeqFile2 are the inputs to Change Capture.
From the output Change Capture Stage we one extra column
‘Change Code’.
If, the record is same in both file, i.e. Copy Record.
Change Code=0
If, the record is only in SeqFile1, i.e. insert Record.
Change Code=1
If, the record is only in SeqFile2, i.e. delete Record.
Change Code=2
If, the record is in both files but with some modifications,
i.e. edit/update Record. Change Code=3

If all Change are '0' then 2 files having same Data.

In the transformer constraints, we can mention as ‘ change
code <>0’ then set ‘Abort After Rows’ to ‘1’.
