R&D Order feature

Dear Cetec Team,

While dealing with an order I saw there is an option to assign a line as “R & D”. I was trying to research the meaning of this feature and I only found this general blog post:

Feature of the Week: Process R&D Orders (cetecerp.com)

Could you please help me understand by elaborating on the use case scenario for the feature? Would all associated costs with an R&D order not appear in the ledgers, or would they be separate? Could I process an R&D order to test that all steps (such as the labor plan) show up properly within the system?

Thanks in advance.
