Update the user log on details in a different system

Hello,

I am working on a requirement where i need to pull records of users in other system from ECC. I found a FM 'SUSR_USERS_GET_FROM_REMOTE' which can retrieve the user details such as valid from , last log on in the other system. My requirement is to update the valid to of the user in the other system through my program. I could not find a FM which can do this task. Can some one help me to find a solution to update the user logon details in the other system from ECC?

Tnx,

Prem
