• What is the cause and solution for SAP error message /SCWM/SHP_RCV070 - User &1 is blocking assignments between delivery/HU and TU ?

  The SAP error message /SCWM/SHP_RCV070 indicates that a user is blocking the assignments between a delivery handling unit (HU) and a transportation unit (TU). This typically occurs in the context of warehouse management and logistics processes within the SAP Extended Warehouse Management (EWM) module.
  Cause:
  The error is usually caused by one of the following reasons:
  
  User Locking: A user is currently processing or has locked the delivery or handling unit, preventing other users from making assignments.
  Incomplete Processes: There may be an incomplete process or transaction that is holding the lock on the delivery or handling unit.
  System Configuration: There could be configuration settings that are causing the system to enforce locks in a way that is not expected.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Blocking User:
  
  Use transaction code SM12 to check for any locks held by users. Look for locks related to the delivery or handling unit in question.
  Identify the user who is holding the lock.
  
  
  
  Communicate with the User:
  
  If possible, communicate with the user who is blocking the assignment to understand what they are doing and if they can release the lock.
  
  
  
  Release the Lock:
  
  If the user is unavailable or unable to release the lock, you may need to manually delete the lock using transaction SM12. Be cautious when doing this, as it may disrupt the user's work.
  
  
  
  Check for Incomplete Processes:
  
  Ensure that there are no incomplete processes or transactions that might be causing the lock. This could involve checking for open deliveries or handling units that need to be completed or canceled.
  
  
  
  Review System Configuration:
  
  If the issue persists, review the system configuration related to warehouse management and transportation management to ensure that there are no settings that are causing unnecessary locks.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that might address this specific error message or provide additional troubleshooting steps.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (to view and manage locks), VL03N (to display deliveries), and HU02 (to manage handling units).
  User Roles and Authorizations: Ensure that users have the appropriate roles and authorizations to perform the necessary actions without causing locks.
  Documentation: Review SAP documentation related to EWM and transportation management for best practices in managing deliveries and handling units.
  
  By following these steps, you should be able to identify the cause of the error and take appropriate action to resolve it.
