I'm referring to a previous thread:
How to get distinct values of SharePoint column using SSRS. I followed all the steps as set out but when I view my report, the parameter is greyed out. I then downloaded the example
report of Jin Chen. In that report, he suggests a blank parameter label for the main parameter, as well as, a default value for the hidden parameter (which is different from the initial thread posted). When I change my report accordingly,
I get an error: An error occurred during local report processing. MainParameter.
Anyone with suggestions?
