Drafts are useful to prepare in advance for future proposal calls, but it's very important to keep in mind that these documents are provisional and therefore subject to modifications. Only the ones published on "EU Funding and Tenders Portal" once adopted by the EC will be valid and legal. For this reason, it is possible that before approval, there may be changes to topics, descriptions, or scope, or new elements may be added, as well as adjustments on budgets or opening and closing dates of proposal calls.
