A static XLSX file is cataloged via Network Share. It is added to a burst containing a WebI report. Content Grouping is enabled using a Delivery Template configured to use the Excel 2007 format. The following error occurs on the grouping step of the burst:
Error ==> Operation is not valid due to a mismatch in the document version
This issue occurs because BusinessObjects exports only Excel 2007 and the static Excel file is another Excel version (i.e., Excel 2016).
This issue is under investigation.
