Hi Karthi,
Why not use the standard SPL Audit Trail report for Business Partners?
Transaction /SAPSLL/SPL_AT_BP_LO
Program /SAPSLL/SPL_AUDITTRAIL_BP_LO
The main table for the audit trail reports is /SAPSLL/SPLAUD.
If you feel like this report does not meet your requirements please state why and provide more information on the exact data you need.
Best Regards,
Eoin
