• What is the cause and solution for SAP error message L2051 - Transfer rqmnt is referenced in kanban. Reference is lost when deleted ?

  The SAP error message L2051, which states "Transfer requirement is referenced in kanban. Reference is lost when deleted," typically occurs in the context of the Kanban process within SAP's logistics and supply chain management modules. This error indicates that there is a transfer requirement (TR) that is linked to a Kanban container, and if you attempt to delete the TR, it will break the link, which is not allowed.
  Cause:
  
  Linked Transfer Requirement: The transfer requirement you are trying to delete is currently being referenced by a Kanban container. This means that the system is enforcing data integrity by preventing the deletion of the TR, as it would lead to inconsistencies in the Kanban process.
  Process Flow: In a typical Kanban process, transfer requirements are used to manage the movement of materials between locations. If a TR is deleted without addressing its references, it could disrupt the flow of materials.
  
  Solution:
  
  Check Kanban Status: Before attempting to delete the transfer requirement, check the status of the Kanban container that references it. Ensure that the Kanban is not in a state that would prevent the deletion of the TR.
  Remove Reference: If you need to delete the transfer requirement, you must first remove the reference from the Kanban container. This can typically be done by:
  
  Changing the status of the Kanban container to a state that does not reference the TR.
  Deleting or adjusting the Kanban container that is linked to the TR.
  
  
  Use Transaction Codes: You can use transaction codes like PK13N (Display Kanban) or PK12N (Change Kanban) to manage the Kanban containers and their references.
  Consult Documentation: Refer to SAP documentation or your organization's SAP support team for specific procedures related to your version of SAP and your organization's configuration.
