The model to research, in plain terms
Belgium is researched through the Peppol route for public buyers, with regional and federal layers that must not be blended. For Belgium, a rule that applies to one level of government may not apply to another, so the buyer level is a research question, not a detail. For Belgium, ask which level of buyer, which Peppol profile, and which identifiers the buyer requires..
That Belgium model only helps with clear questions. For Belgium, ask which transactions fall in scope. For Belgium, ask which format the route expects. For Belgium, ask what status evidence comes back. A Belgium summary without those answers is unfinished.

For Belgium, record the date beside each answer. A Belgium guide without check dates is a summary. Belgium summaries are where stale claims come from. Dated Belgium checks are the point of this route.

A Belgium rejection should name its rule. A Belgium rejection should name its field. A Belgium rejection should name the value sent. A Belgium rejection should name the value expected. Without those facts, a Belgium rejection is a delay. Return a Belgium rejection with that request.
Evidence for Belgium is what remains afterwards. Keep the Belgium invoice as exchanged. Keep Belgium status messages with it. Keep any Belgium correction linked to it. A Belgium auditor asks for that set.
