Hi Experts,

I am facing one issue in analysis for Excel workbook in BW. I have created workbook by inserting many Queries and Linking it to different sheets. This workbook was refreshed successfully on 2nd June 2021 but when I want to refresh the same in Mid June. It is not getting refreshed. My Analysis for office version is 2.8.100.92864. If any one has faced this issue, please help in solving this issue.
