Check UserID of the entity who has updated the PI tag

Hello,

Is there any way to check the user's ID who has updated a particular PI tag?

I am using PI-SDK and OLEDB queries to update PI tags in a .Net application, where I need this.

For example: If I am logged in to my windows account- "GuestUser" and I opened the application and updated any particular PI tag, is there any way to trace the user ID?

I tried using "Message Logs" in PISDK utility but not found anything such.

Thanks,

Souvik
