Extensibility feature is not yet supported for report objects in Business Central. But, now So now we can substitute reports from the Base application with Custom reports.
To substitute a report, we have to create a method and subscribe it to the OnAfterSubstituteReport event published by Codeunit 44 – ReportManagement.
This method replaces the report specified by the ReportId with the one given by the NewReportId parameter.
In this example the “Customer – List” report will be substituted for “My New Customer – List”
When the “OnAfterSubstituteReport” event is raised, the event subscriber method is called, and the replacement takes place.
