• What is the cause and solution for SAP error message /CWM/MM002 - No handling units exist for the selected line ?

  The SAP error message /CWM/MM002 No handling units exist for the selected line typically occurs in the context of handling units (HUs) in the Warehouse Management (WM) or Extended Warehouse Management (EWM) modules. This error indicates that the system cannot find any handling units associated with the selected line item in a document, such as a delivery or a transfer order.
  Causes:
  
  
  No Handling Units Created: The most common cause is that no handling units have been created for the line item in question. This can happen if the goods have not been packed or if the packing process was not completed successfully.
  
  
  Incorrect Document Status: The document may be in a status that does not allow for handling units to be created or processed.
  
  
  Data Inconsistencies: There may be inconsistencies in the data, such as missing or incorrect entries in the database that prevent the system from recognizing the handling units.
  
  
  Configuration Issues: There may be configuration issues in the WM or EWM settings that affect how handling units are managed.
  
  
  User Authorization: The user may not have the necessary authorizations to view or manage handling units.
  
  
  Solutions:
  
  
  Create Handling Units: If no handling units exist, you may need to create them. This can typically be done through the packing process in the relevant transaction (e.g., using transaction code HU02 for handling unit management).
  
  
  Check Document Status: Ensure that the document (e.g., delivery or transfer order) is in the correct status to allow for handling unit processing. If necessary, change the status or complete any required steps.
  
  
  Review Data: Check for any inconsistencies in the data related to the line item. This may involve reviewing the material document, delivery, or transfer order to ensure that all necessary information is present and correct.
  
  
  Configuration Review: If you suspect a configuration issue, consult with your SAP WM/EWM configuration team to ensure that handling unit management is set up correctly.
  
  
  User Authorization: Verify that the user has the necessary authorizations to access and manage handling units. This may involve checking user roles and permissions in the SAP system.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as HU02 (Handling Unit Management), VL02N (Change Outbound Delivery), and LT03 (Create Transfer Order) for managing handling units and related documents.
  SAP Notes: Check SAP Notes for any known issues or patches related to handling units and the specific error message.
