• What is the cause and solution for SAP error message /SCWM/MFS421 - Realignment for HU &1 necessary (Moves: &2 / Max. moves &3) ?

  The SAP error message /SCWM/MFS421 Realignment for HU &1 necessary (Moves: &2 / Max. moves &3) typically occurs in the context of the SAP Extended Warehouse Management (EWM) system, particularly when dealing with Handling Units (HUs) and their movements.
  Cause:
  This error message indicates that a realignment of the Handling Unit (HU) is necessary due to the number of moves associated with it. The message provides the following details:
  
  HU &1: The specific Handling Unit that requires realignment.
  Moves: &2: The current number of moves associated with the HU.
  Max. moves &3: The maximum number of allowed moves for the HU.
  
  The realignment is necessary when the number of moves exceeds the predefined limit set in the system. This can happen due to various reasons, such as:
  
  Frequent changes in the status or location of the HU.
  System configuration settings that limit the number of moves for a single HU.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Configuration Settings:
  
  Review the configuration settings for Handling Units in your SAP EWM system. Look for parameters that define the maximum number of moves allowed for HUs.
  If necessary, adjust the configuration to allow for more moves if it aligns with your business processes.
  
  
  
  Perform Realignment:
  
  Execute the realignment process for the specified Handling Unit. This can typically be done through the EWM interface where you can find options to realign or manage HUs.
  Ensure that the HU is in a state that allows for realignment (e.g., not locked or in a process that prevents changes).
  
  
  
  Review HU Movements:
  
  Analyze the movements associated with the HU to understand why the limit was exceeded. This may involve checking the history of the HU and identifying any unnecessary or excessive movements.
  If certain movements are not needed, consider reversing or consolidating them.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed guidance on handling HUs and managing their movements.
  
  
  
  Contact SAP Support:
