Extending AL object, Global Vars Vs Protected Var
Developers sorry for my ignorance. Microsoft explain clear and to the Definition it should be correct (protected vars are “protected”). However, when extending a report for example I can find only protected variables and not Globals. I am doing something wrong. Any setup in VS Code?
Microsoft or Copilot says…
In Business Central, the difference between global vars and protected vars is significant:

This distinction is crucial for managing data access and extensibility in Business Central applications.

Hello Again
And the definition as per Microsoft is clearer and behavior as per design, however the naming convention is not user friendly. The concern in here is, why I cannot extend the other Global Vars? In some cases, we need them and extending is not an option, instead we need to create a copy of the object to developed a new report or object. And the worst part is when the object we want to extend is from another partner or add on.
Microsoft link says:
The protected keyword can be used to make variables accessible between tables and table extensions, pages and page extensions and reports and report extensions. It also makes variables accessible between extensions if they belong to apps, which depend on each other. If you want to only expose some variables as protected, you must create two sections of var declarations.
