  The SAP error message /SCWM/HU_WM091 Planned shipping HU &1 already exists typically occurs in the context of handling units (HUs) in the SAP Extended Warehouse Management (EWM) module. This error indicates that there is an attempt to create a planned shipping handling unit (HU) that already exists in the system with the same identifier.
  Cause:
  
  
  Duplicate Handling Unit: The most common cause of this error is that a handling unit with the same identifier (e.g., HU number) is already present in the system. This can happen if:
  
  The HU was created previously and not properly closed or deleted.
  There is a system error or inconsistency that leads to the HU being recognized as existing.
  
  
  
  Incorrect Data Entry: Sometimes, the error can arise from incorrect data entry or configuration settings that lead to the system attempting to create a duplicate HU.
  
  
  Solution:
  
  
  Check Existing HUs: 
  
  Use transaction codes like /SCWM/HU or /SCWM/PR to search for existing handling units in the system. Look for the HU number mentioned in the error message.
  If the HU exists and is not needed, consider deleting or closing it properly.
  
  
  
  Review HU Creation Process: 
  
  Ensure that the process for creating planned shipping HUs is being followed correctly. Check for any custom developments or enhancements that might affect HU creation.
  
  
  
  Use Unique Identifiers: 
  
  If you are generating HUs programmatically, ensure that the logic for generating HU numbers guarantees uniqueness.
  
  
  
  Consult Logs and Documentation: 
  
  Check system logs for any additional error messages or warnings that might provide more context about the issue.
  Review SAP documentation or notes related to handling units and planned shipping to ensure compliance with best practices.
