hi Nithya,
also you can Try to execute the report RSUSR200 to check for the user data.
you will find the last logon of the user and that will.
Also you can check table at USH02 / USH04 for the deleted user, there will be an entry of the last logged in date, including the last time.
In the last date entry, check for user with entry to tcode: KRNL and Program: SAPMSYST.
SAP writes this entry form USR02 to USH02 before it deletes the record for the user.
Please find below thread for more reference.
Last time a deleted user accessed the system
Let us know if this helped you.
