I went and changed all of my stored proc datatype to nvarchar instead of GUID and allow NULL.
I was able to see the data when i clicked on "Main Report Preview".
But when i run the report from my web app, I received this error.
One or more fields could not be found in the result set. Use Verify Database to update the report. Error in File C:\DOCUME~1\HyVong\LOCALS~1\Temp\4\StandardPartSummaryReport {6F44DA3D-7290-49DC-B5E2-7F734A4D6C8F}.rpt: The rowset column could not be found.
But i verified the database, and i tried to use only 1 field from the report and still receiving this error. Does anyone knows why? is it because the value i passed into the report are not coming through and therefore my report couldn't retrieve any record from the database?
If i don't select any field to display on my report, then the report works, but as soon as i select a field from the 'Database field' i get this error.
I am new when it comes to hooking up CR with stored proc, perhaps somebody out there can help me. I have been struggle through this for days.
Thanks in advance!
