Is PINT-OM the same as a provider API?

Not necessarily. A provider API may wrap or add transport fields around the governed invoice model.

Can one ERP mapping serve every entity?

Shared mapping is possible, but entity registrations, numbering, tax data and local process differences still need configuration and testing.

Keeping country-specific mapping in a middleware layer usually reduces ERP change and makes version management clearer.

Assess the version change, update mappings and validation, run regression tests and coordinate production activation with the provider.
