We are using MS Excel 2007 Pivot tables to access en SSAS 2005 Cube. Farly often when we reopen an excel spreadsheet with one or more pivot tables we get an error like this:
Excel found unreadable Content. Do you wish to repair
When we click yes the following log is shown:
Removed Feature: PivotTable report from /xl/pivotCache/pivotCacheDefinition1.xml part (PivotTable cache)
Removed Feature: PivotTable report from /xl/pivotCache/pivotCacheDefinition2.xml part (PivotTable cache)
Removed Feature: PivotTable report from /xl/pivotTables/pivotTable1.xml part (PivotTable view)
Removed Feature: PivotTable report from /xl/pivotTables/pivotTable2.xml part (PivotTable view)
Removed Records: Workbook properties from /xl/workbook.xml part (Workbook)
And all the pivot tables are converted to plain text.
I have read about this in KB 929766 but this do not apply since KPIs are not used.
The KB 943088 is more interesting but after upgrading all user with SP 1 the problem is still there, mostly when we open old excel-files that has been created without SP 1 but opened and saved once with SP 1. After that we are not able to open them at all, either with or without SP 1 installed.
Is there some way to “save” pivot tables from destruction? I can’t ask the users to rebuild all there spreadsheets that have been created prior SP1. What will happen when there is a new SP for Excel? Rebuild all spreadsheets and pivot tables again?
