3809353 - Analysis for Office refresh error - Object reference not set to an instance of an object

• When reopening and refreshing a saved workbook, one data source fails with error: [5a73-4c85-1b] Object reference not set to an instance of an object.
• The affected crosstab is not rendered and its range collapses from several rows/columns to a single cell.
• Other data sources in the same workbook refresh successfully and Refresh All reports success.
• Observed in different workbooks by different users.
• The failure occurs only on the data source that has saved expanded hierarchy nodes (persisted drill state).
• SU53 shows "Authorization check not successful" for RFC function module BICS_PROV_GET_HIERARCHIES, however authorizations seem to be as expected

• Analysis for Office 2.8
