I am trying to modify an existing report to allow the user to enter multiple user id's to a report. Currently, the report will allow you to filter by one user id, but I need to have it filter by more than 1. I changed the parameter to 'allow multiple values'. I then changed the query to IN(@parameter) instead of =@parameter. Now when I attempt to run the report I get "The report parameter has a defaultvalue or a validvalue that that depends on the report parameter. I changed the order of the parameters and still get this error. My report consists of open Purchase Orders. It originally was set up to enter in a buyer id. After that was established then it would allow you to select what supplier id(s) you wanted to filter by. I am doing all of the editing in Visual Studio 2012, then it gets deployed and ran on Report Manager. Copy-of-Expedite-Report-by-Buyer.rdl Expedite-Report-by-Buyer.rdl
