  Check Assignments: Review the assignments of the alternative items in the BOM or the relevant structure. Ensure that all alternative items are linked to the same process element.
  Modify BOM: If necessary, modify the BOM to ensure that the alternative items are correctly assigned. This may involve editing the BOM in the SAP GUI or using transaction codes like CS02 (Change BOM).
  Review Process Elements: Ensure that the process elements are correctly defined and that the alternative items are intended to be used in the same context.
