• What is the cause and solution for SAP error message GK649 - Item and item hierarchy cannot be entered simultaneously ?

  The SAP error message GK649 ("Item and item hierarchy cannot be entered simultaneously") typically occurs in the context of creating or modifying a document in SAP, such as a purchase order, sales order, or other transactional documents where item details are specified. This error indicates that the system does not allow the simultaneous entry of both individual items and item hierarchies in the same document.
  Cause:
  
  Simultaneous Entry: The error arises when a user attempts to enter both a specific item (material number) and an item hierarchy (a group of items) in the same line of a document. SAP requires that you choose one or the other.
  Configuration Settings: The system configuration may not allow for the combination of item types in certain transactions, leading to this restriction.
  Data Entry Error: It may also be a result of a data entry mistake where the user inadvertently selects both options.
  
  Solution:
  
  
  Review Document Entry: Check the document you are trying to create or modify. Ensure that you are only entering either an individual item or an item hierarchy, but not both.
  
  If you need to use an item hierarchy, remove any individual item entries.
  If you need to specify individual items, ensure that you are not selecting an item hierarchy.
  
  
  
  Adjust Configuration (if applicable): If you believe that the configuration should allow for both entries, consult with your SAP administrator or technical team to review the settings related to item entry in the relevant transaction.
  
  
  Training and Documentation: Ensure that users are trained on the correct procedures for entering items and item hierarchies in SAP to avoid this error in the future.
  
  
  Related Information:
  
  SAP Documentation: Refer to SAP Help documentation for specific transaction codes and guidelines on item entry.
  Transaction Codes: Familiarize yourself with the relevant transaction codes (e.g., ME21N for purchase orders, VA01 for sales orders) and their specific requirements regarding item entry.
  SAP Notes: Check SAP Notes for any updates or patches that may address this issue or provide additional guidance.
  
  If the problem persists after following these steps, it may be beneficial to reach out to SAP support or your internal IT team for further assistance.
