+- Extension objects cannot declare the `Permissions` property.
+- The method-level `[InherentPermissions]` attribute only accepts objects from the same extension, so pointing it at a Base Application table fails with [AL0720](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/diagnostics/diagnostic-al720).

+For the same reason, the code fix is not offered on extension objects. To comply, move the data access into an object that can declare `Permissions`, such as a codeunit, and call it from the extension.

+Allowing the `Permissions` property on extension objects is an open request to Microsoft: [Set permissions on page- and table extensions](https://experience.dynamics.com/ideas/idea/?ideaid=9402e200-a6e5-e911-b3b9-0003ff68a105). It is marked as needing votes and is not on Microsoft's roadmap yet, so add your vote if this affects you.
