As identified during workshops, standard solutions (S/4 + Ariba) do not fully cover the required collaboration scope, especially for:
Therefore, a custom SAP BTP Supplier Portal is introduced as the primary interaction channel
The scope is aligned with the “orange areas” from the functional scope diagram below
