Thanks for your quick response. Here are the details.

10m file is the parent file in which id is key record. each id record in parent file has 6 sub records in the 90m file. out of which, the program picks only 3 sub records which are not contiguous.

Also, this program does not do any update, insert or delete to the IAM files. Delete define is not happening in this job.
