Is there any way to hide some specific prompt

Hi Gurus

In our scenario BO platform integrate with custom portal, and portal users are n:1 with BO user, now we want to send some user attribute which define and set value in portal to WEBI report, also we do not users to modify these value.

We try to use opendocument with lsS parameter to sent these variable to WEBI, it refresh ok in the first time, but when user click refresh button, they can modify value of prompt.

Since portal user not 1:1 with BO user, so we can't use BO user attribute and make it equal to Portal User attribute.

Can anyone have idea to solve this request?

Is there any way to hide some specific prompt?
