SysDictClass object not initialized while running SSRS report, help!

Hi, I have created a SSRS report using a Data provider class that uses a Stored procedure to fill a temp table and the display the fields, I’m using two AX environments, it works in the test one, but when I move to a different environment (let’s call it production) I get this error:

I don’t know what to do, as I said, it works fine in the test environment, but not in the second one, and they are the same, any idea? I already redeployed the SSRS report in the AOT, but nothing, thanks in advanced!!
