• What is the cause and solution for SAP error message L3420 - Currently, only handling units for deliveries can be moved ?

  The SAP error message L3420, "Currently, only handling units for deliveries can be moved," typically occurs in the context of handling units (HUs) and inventory management within the SAP system. This error indicates that the system is trying to perform an operation (like moving or transferring a handling unit) that is not allowed for the current context, which is usually related to the type of document or the status of the handling unit.
  Cause:
  
  Incorrect Document Type: The operation you are trying to perform is only valid for handling units associated with deliveries. If you are trying to move handling units that are not linked to a delivery (e.g., stock transfer orders, production orders), this error will occur.
  Status of Handling Unit: The handling unit may be in a status that does not allow it to be moved. For example, if the handling unit is already in a process that locks it for movement.
  Configuration Issues: There may be configuration settings in the system that restrict the movement of handling units based on certain criteria.
  
  Solution:
  
  Check Document Type: Ensure that the handling unit you are trying to move is associated with a delivery. If it is not, you may need to create a delivery for the handling unit or use a different process that is appropriate for the type of document you are working with.
  Review Handling Unit Status: Check the status of the handling unit. If it is locked or in a status that prevents movement, you may need to change its status or complete any outstanding processes before attempting to move it.
  Use Correct Transaction: Make sure you are using the correct transaction code for moving handling units. For example, use the appropriate transaction for delivery-related movements.
  Consult Configuration: If you suspect that the issue is related to system configuration, consult with your SAP Basis or configuration team to review the settings related to handling units and their movement.
