#11967 Block Edit in Excel for pages based on the User table

Edit in Excel now blocks page-based editing for tables that are the User table to prevent authentication corruption when users are edited via Excel and published back. A new check in the Edit in Excel implementation logs telemetry and raises an error before workbook generation.

What changed

  • Adds CheckPageIsSupported to codeunit 1482 (Edit in Excel Impl.), which blocks pages whose source table is User
  • The check runs in all three entry points, and in EditPageInExcel it runs before the web service is created and before OnEditInExcelWithFilters is raised
  • The check uses the source table, so it covers every page over User and renamed or localized *_Excel web services can’t bypass it
  • When the check blocks a page, it logs telemetry 0000U9E and shows an error
  • This is a mitigation only: workbooks already downloaded and existing Users_Excel web services can still publish changes
  • Behaviour changes for users or extensions.
