Unable to remove user in Windchill

Hi All,

Good Day To You..

I've removed Windchill  existing user normaly. But, still that user is existing in products context. I've checked in LDAP, where no such user was observed.

But, from SQL Server, by executing a query, I've found that user from WTUser table.

I need your help for permanently remove that user.

Thanks And Regards
