• What is the cause and solution for SAP error message /SCWM/WHO421 - A warehouse order should be added to higher-level WO &1 ?

  The SAP error message /SCWM/WHO421 A warehouse order should be added to higher-level WO &1 typically occurs in the context of SAP Extended Warehouse Management (EWM) when there is an issue with the hierarchy of warehouse orders (WOs). This error indicates that the system expects a certain warehouse order to be associated with a higher-level warehouse order, but it is not.
  Cause:
  
  Hierarchy Misconfiguration: The warehouse order you are trying to process is not correctly linked to its parent warehouse order.
  Incomplete Processing: The higher-level warehouse order may not have been fully processed or released, leading to the inability to associate lower-level orders.
  System Configuration: There may be configuration settings in the EWM that dictate how warehouse orders should be structured and processed.
  
  Solution:
  
  Check Warehouse Order Hierarchy: Verify the hierarchy of the warehouse orders. Ensure that the lower-level warehouse order is correctly assigned to the higher-level warehouse order.
  Release Higher-Level Warehouse Order: If the higher-level warehouse order is not released, ensure it is released and processed before attempting to add lower-level orders.
  Review Configuration Settings: Check the configuration settings in the EWM to ensure that they align with your warehouse processes. This may involve reviewing the settings for warehouse order creation and processing.
  Use Transaction Codes: Utilize relevant transaction codes (like /SCWM/WO for warehouse orders) to view and manage the orders. This can help in identifying any discrepancies.
  Consult Documentation: Refer to SAP documentation or help notes related to warehouse order processing for additional insights and troubleshooting steps.
