I have total 4 Tablix in my SSRS Report. One for PDF report and Rest three Tablix for three excel tabs : Details, total and Grant Total. My PDF report is as expected. Howeve, excel report generates additional tab named "Sheet1".
I have no clue where this Sheet1 is coming from. I have searched the rdl.xml file with string "sheet1" , but could not find any match.
Please let me know if you can guess what might be the problem.
