Is there a way to track the N (recordmode value) created record date, first request. I could not find in the system.
Get the request number (ODSR*) for the N-record. Go back to the manage screen, in the Requests tab scroll all the way to the right. There you'll see a column containing the ODSR* request numbers. Find the above request number in this column and check the date. Alternatively go to RSODSACTREQ, put the ODSR* number and you''ll get the timestamp of the request.
Why in the same request, it creates 3 records with N(recordmode), what are the chances ?
The three records would be having different values in the key fields of the DSO.
