2212661 - MRP: Source of supply, several valid source list


  • Several sources of supply are marked in the source list as relevant for materials planning. The validity period of the sources of supply overlap. In this situation, no source of supply is assigned to the procurement proposal in the MRP run, or it is not possible to predict which source of supply is assigned.
  • Also setting the 'Fixed source of supply' indicator does not change this behavior for an entry in the source list.
  • If the validity period does not overlap, the source of supply is assigned correctly.
