If several of your entities (manufacturer, seller and payee) shares the same 4-digit Supplier ID given by Scania, you are also required to add a count digit or something that differentiates the Master Data entities in the portal in the "Global ID" field.
This could for example be your own internal ID for each entity or simply a count digit for each MD that share same local ID (first master data gets "1", second "2" etcetera.
