Caching a report with parameters

I have two reports one with no parameters and one with two parameters that
uses a data source with credentials stored.
When I try and setup caching for these reports I cannot for the one with
parameters. I get an error:"Credentials used to run this report are not
stored" even though they are.
Is this by design or do I need to do soimething else.
ThanksIt is by design. See my post
