What posting registers
Posting creates a registration with status Awaiting Contract.
When you post a sales invoice, sales credit memo, purchase invoice, or purchase credit memo, the app registers it for the archive. The status is Awaiting Contract.
Posting still finishes if that registration cannot be written. Registering the same document again does not create a second row.
If the registration is missing, open the posted document and choose Register Archive Foundation. An existing registration is reused.
