SSRS PARAMETER ERROR

When  develop a report in VS, and execute it..it runs perfectly as expected. However, when I deploy the report to execute on the portal, the following error appears:

An error has occurred during report processing. (rsProcessingAborted)
An attempt was made to set a data set parameter '@' that is not defined in this data set. (rsUnknownDataSetParameter)

Please is there anything I may have missed out?

Hello,

There may be two reasons the parameter is not correctly bound with dataset or since parameter is case sensitive this can happen.

Hope this below link will let you overcome the error.

I have a report developed with MS Visual Studio, when I preview it, it works fine.

When I deploy it on to the live SSRS web portal, the following error appears.

An error has occurred during report processing. (rsProcessingAborted)
An attempt was made to set a data set parameter '@' that is not defined in this data set. (rsUnknownDataSetParameter)
