Comment a WebI-Document with currentUser and currentDate functions

Hi experts,

I want to comment a WebI document with less effort. I used this (Enabling Comments in Web Intelligence Reports using Input Controls) solution and everything works fine:

In addition to this solution I would like to insert the current user and the current time for the comment.

Obvious I can’t handle this with the functions currentUser() und currentTime(). Because with each interaction or regeneration of the report the function values would be changed.

Is there anybody how knows a solution to store the currentDate and currentUser values persistent in the report, without inserting these values manually?

Thanks a lot,

Sebastian
