Archived products cannot be modified by design. There are several reasons for this:
An archived product in Keyline is considered complete in both business and technical terms. At this point, all calculation, production and billing data represent the binding actual state. If subsequent changes were allowed, post-calculations, reports, analyses and accounting data would no longer be consistent.
In addition, Keyline works with clearly defined states and events (e.g. for production, invoicing and API integrations). Rolling back or changing archived products would break this process logic and external connections (webhooks, API, reporting).
In short:
đ Archived = revision-safe and final.
This keeps figures, processes and analyses reliable.
If technical details need to work differently in future, we recommend:
a new product template, or
a new product / follow-up order based on the archived data.
