• What is the cause and solution for SAP error message /SCWM/HUGENERAL191 - HUs whose assignment was deleted can no longer be assigned ?

  The SAP error message /SCWM/HUGENERAL191 indicates that Handling Units (HUs) whose assignment has been deleted can no longer be assigned. This error typically arises in the context of Warehouse Management (WM) or Extended Warehouse Management (EWM) when there is an attempt to reassign or manipulate a Handling Unit that has already had its assignment removed.
  Cause:
  
  Deleted Assignment: The primary cause of this error is that the Handling Unit has had its assignment deleted, which means it is no longer linked to any stock or location in the warehouse.
  Incorrect Process Flow: The error may occur if the process flow is not followed correctly, such as trying to reassign an HU that has been marked for deletion or has already been processed in a way that invalidates its current assignment.
  System Configuration: There may be configuration settings in the SAP system that restrict the reassignment of HUs once they have been deleted.
  
  Solution:
  
  Check HU Status: Verify the status of the Handling Unit in question. If it has been marked as deleted, you will need to create a new Handling Unit or restore the original assignment if possible.
  Recreate the Handling Unit: If the HU cannot be reassigned, consider creating a new Handling Unit and assigning it to the desired stock or location.
  Review Process Steps: Ensure that the process steps leading to the assignment of HUs are being followed correctly. This includes checking for any prior steps that may have inadvertently deleted the assignment.
  Consult Documentation: Review SAP documentation or help resources for specific guidelines on handling HUs and their assignments.
  System Configuration: If the issue persists, consult with your SAP Basis or configuration team to review the settings related to Handling Units and their assignment processes.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SCWM/HU for Handling Unit management, and /SCWM/PR for managing stock in EWM.
  SAP Notes: Check for any SAP Notes related to Handling Units and error messages for potential bug fixes or updates.
  User Roles and Authorizations: Ensure that the user has the necessary authorizations to perform actions on Handling Units, as restrictions may lead to errors.
  Training and Documentation: Consider additional training or documentation for users involved in warehouse operations to minimize errors related to Handling Unit management.
