This correction is for the separate condition: A fiscal app requires a default setup row the first time it is installed for a customer. It would not directly restore the intended behavior in this situation: A logistics vendor must swap carrier pricing implementations based on an enum selection while calling the same method signature. Here, align the codeunit implementations with the interface method signatures and correct provider selection, because interfaces define a contract and enable polymorphic dispatch without hard-coding a concrete provider into every caller.

This correction is for the separate condition: A vendor moves invoice surcharge settings from one table to another in a new app version. It would not directly restore the intended behavior in this situation: A logistics vendor must swap carrier pricing implementations based on an enum selection while calling the same method signature. Here, align the codeunit implementations with the interface method signatures and correct provider selection, because interfaces define a contract and enable polymorphic dispatch without hard-coding a concrete provider into every caller.

This correction is for the separate condition: Three extensions all implement the same freight-cost calculation with small inconsistent differences. It would not directly restore the intended behavior in this situation: A logistics vendor must swap carrier pricing implementations based on an enum selection while calling the same method signature.

This choice primarily fits a different requirement: A new extension needs initial configuration records when first installed into a tenant. There, an install codeunit performs initial tenant setup; repeated deployment must not reinitialize established user data. In the current situation, A tax add-on supports multiple rule providers that all expose the same calculation contract. Interfaces define a contract and enable polymorphic dispatch without hard-coding a concrete provider into every caller. Acceptance requires switching the selected provider changes implementation while all callers use the same documented interface.

This choice primarily fits a different requirement: A version update renames the internal customer loyalty schema and existing data must be carried forward. There, upgrade codeunits are designed to transform previously installed extension data when application versions change. In the current situation, A tax add-on supports multiple rule providers that all expose the same calculation contract. Interfaces define a contract and enable polymorphic dispatch without hard-coding a concrete provider into every caller. Acceptance requires switching the selected provider changes implementation while all callers use the same documented interface.

This choice primarily fits a different requirement: Several AL pages duplicate the same invoice validation code and it behaves differently in each copy. There, codeunits encapsulate callable al business logic independent of a page's visual layout. In the current situation, A tax add-on supports multiple rule providers that all expose the same calculation contract. Interfaces define a contract and enable polymorphic dispatch without hard-coding a concrete provider into every caller. Acceptance requires switching the selected provider changes implementation while all callers use the same documented interface.

That mechanism explains why the alternative action—use an install codeunit and guard setup initialization for first installation—helps in another case. It does not justify the proposed fix here; interfaces define a contract and enable polymorphic dispatch without hard-coding a concrete provider into every caller. The distinguishing requirement is: A tax add-on supports multiple rule providers that all expose the same calculation contract.

That mechanism explains why the alternative action—implement a controlled upgrade codeunit to migrate records during extension upgrade—helps in another case. It does not justify the proposed fix here; interfaces define a contract and enable polymorphic dispatch without hard-coding a concrete provider into every caller. The distinguishing requirement is: A tax add-on supports multiple rule providers that all expose the same calculation contract.

That mechanism explains why the alternative action—extract the shared business logic into a codeunit with reusable procedures—helps in another case. It does not justify the proposed fix here; interfaces define a contract and enable polymorphic dispatch without hard-coding a concrete provider into every caller. The distinguishing requirement is: A tax add-on supports multiple rule providers that all expose the same calculation contract.

This would verify use an install codeunit and guard setup initialization for first installation, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: A tax add-on supports multiple rule providers that all expose the same calculation contract. The decisive local proof is switching the selected provider changes implementation while all callers use the same documented interface.

This choice primarily fits a different requirement: A version update renames the internal customer loyalty schema and existing data must be carried forward. There, upgrade codeunits are designed to transform previously installed extension data when application versions change. In the current situation, A new extension needs initial configuration records when first installed into a tenant. An install codeunit performs initial tenant setup; repeated deployment must not reinitialize established user data. Acceptance requires a fresh install creates defaults while an upgrade leaves existing configured values untouched.
