ITS Custom Login screen password expirey option?

Hi all,

We have included the custom login screen in the ITS service. By using login and password parameters in the service parameters.

But in this the new custom login screen doesn't have the new password option or it cannot detect the password expiry of the sap users login into the ITS service.

Can anyone please let me know which system variable handles the password expiry for the SAP login.

Or can anyone let me know the standard program for the ITS SAP standard login screen.

Thanks Urgent requirement. rewards will awarded for the all the responses

Thanks & Regards

Ekta
