I have copied a Sp and have added a column in the new version. I am now trying to update the report with the new Sp. I go through the set datasource location, point to the new Sp and click Update. When I close the datasource location window I get a small windows with the following error:
Invalid Argument provided
How can I find out what 'argument' this is pointing to and the reason for the error. I really don't want to have to rebuild the report as I have around 50 report Sp's to do this to.
