Last Logon date and Logon time not updating in table USR02

Hi,

Please help us on this. After customer successfully logged in the webshop, we are checking the table USR02 in CRM system and the Logon date and Logon time is not updated. Because of this, the customer will be locked after certain number of days. When we check it in ECC system, customer's last logon date and time is updated. Can you tell us what could be causing this? Any advise what we need to check? Thanks in advance!

Regards,

Mike
