Answer 1

I just had this same problem during a SSRS development of a Custom Report for MS CRM Dynamics 2011.

The reason because it occurred is because I am using some Hidden Parameters and for some of them I forget to give a default value.

So, because of I have few time to finish the report I forget to put the default value for some Parameters and I risked to lost more time to fix it.

Luckily I found it very fast because the error shows the textbox and the paragraph with the first wrong parameter but it didn't shows the name of the parameter:

"I cannot post the image of the error because this website don't allows me"

In general during SSRS developments it's very important to remember: - To put the report parameters in the correct sequence (the referred ones for first es. parameters inherited from master report or parameters essentials for sub-datasets) - To assign a default value to the Hide and Internal Parameters.
