I have a report, and it calls a stored PROC. My dataset was bound to this pulling in (for example) three fields. I have now updated this proc to pull a few more additional fields. I refreshed the DataSet to pull the new fields, and in my "Report Data" window, these changes can be seen. I cannot figure out how to update the Tablix to show the new fields.
The closest I can find anyone referring to this is in threads like this, but they all seem to refer to how to update the DataSet. For me, the set has been updated already (via refresh fields), the new fields are not coming through.
