Report provider class cannot contain multiple parameters with same name.

Hi,

Anyone can give light about this issue, I tried to refresh dataset on the report designer, then I got this error "Report provider class cannot contain multiple parameters with same name paramName". I deleted all parameters but still the same error.

    There are two sets of parameters. There is one parameter node for the whole report and then one parameter node for each dataset. Please make sure that you've cleaned up both.

    Is your contract class being used in your DP class properly compiling?  Also, when you say you deleted all the parameters, you are referring that you deleted them from the SSRS report - Parameter section?

    Hi Martin,

    Yes, both are cleared properly, also I restart the AOS service to refresh but still same problem.

    Weird thing is when I tried to import back the VS Project backup, it did not change, still the same ssrs report design.

    Hi Iulian,

    Yes, contract class is being used in DP class and properly compiled.

    Yes, I was referring on deleting parameters from the SSRS report - Parameter section.

    Do a complete refresh of the components, meaning restart the SSRS service, AOS, and then in AX do a Tools -> Caches -> Refresh elements and Refresh report server.

    Hi Iulian,

    I followed on your instruction but still the same, also I tried to removed the contract class in DP class but still the same.

    Thanks,

    Can you show us your RDP class? The problem seems to be there. Also try restarting AOS after changing your RDP class; it's possible that the metadata service returns outdated data from cache.

    Do think license for "Enable License code for authoring and editing" can cause this error. Also when I edit a class the model is still the same "Foundation" and not changing to CUS.

    I created new DP class, but when I browse it in the Report designer dataset Query properties, new DP class is not on the list, I tried to restart AOS but still the same.

    No, that code in the license is not causing this.

    Now you are starting to describe a somehow different situation. For a DP class to be visible in the VS DP list it has to inherit one of the SRSDataProvider* classes, also to have specific attributes to describe the contract class SRSReportParameterAttribute(classStr(ContractClass)), maybe the query, etc. Have you done that?

    Also, a standard class edited by you will still show on Foundation, only the tree nodes changed by you will show the  new model.

    Hello,

    1. Can you please try to create new dataset & put RDP classname and check.

    2. If you have parameters in Contract class and you are using that in RDP class then please write a simple job and call your report class & check. You will get whether you are facing issue. If its not help then please put your contract class method and processReport of RDP class.
