Huh??? You only return data that has been filtered by the SP to CR but you want all of the records?
Filtering is done Server side with SP's, if CR doesn't get the unfiltered data then you have to change it server side.
So first suggestion is to remove the parameters from the SP, then CR can filter or not later on but could potentially return a lot of data. Applying filtering client side in CRD coudl take a while to do, depending on what is in the report....
