We have installed sp2 couple of weeks back in our dev environment which has reporting services as well. I cannot get Select All option when I select Multi-value parameter in the parameter section. Here is what I did... 1.) Created a dataset with the available values. 2.) Created a prameter from the stored procedure. 3.) Selected the parameter and clicked Multivalue and selected the From query from the available values and selected appropriate dataset and value field. 4.) Clicked OK. Thats it. This is what I did prior to SP1 and it worked with the Selecte All functionality and now with SP2 it should work the same way. Did I miss anything. Please help.
