Bypass the error messages while opening the Web Analysis 9.3.1 Report

Question

I am using WA 9.3.1 to create a few reports. The login users will have some essbase meta-read security filters to restrict the access into certain regions and entities.
For example:
user a has the meta-read and read access of @idescendants (east);
user b has the meta-read and read access of @idescendants (west);
user c has all the accesses
However, in the first start-up page (Web Analysis 9.3.1 dashboard), I have a dashboard which contains all the regions access. When user a login, he shall only see his own dashboard (speedometers, etc.).
Currently the user login will get some error messages (such as "loading document produce error", etc). I wonder whether we can set the message level in Web Analysis so that there is no such error message while the user is opening the reports.
Thanks

Karen,
Thanks for the reply.
I have checked my Web Analysis report, and I still have the error message of "Error Occur while opening document. Document ID = {0}" while using the some user id to login.
In my Web Analysis database connection preference, my setting is "user the user id and password". I have verified this (when I use "user a" to login, and in essbase connection, i can see the session with "user a").
In the WA report, however, I use the multiple-level combo box, so that it can give me different levels of entities, for example, the top level is all regions, the 2nd level is east/west/south/ ec, and the next level is cities, and so on. And if "user a" login, he will be able to see the all regions and east, and then east cities (of course, if he select all regions, there will be no data available).
Do you think this multiple level combo boxes can be the cause of this error message?
Thanks a lot
