HI Sudharshan,
Yes you are correct. INSDES is not present for D98B. Could you let me know what is the subversion for the INSDES payload which you are using. Also, if possible I request you to share the payload with me so that I can check on our systems. If you are not willing to put the payload on SCN then you can mail it to me "ruchir.sinha@sap.com".
Best Regards,
Ruchir
