  The SAP error message /SCWM/UI_ADMA027 No source handling unit exists typically occurs in the SAP Extended Warehouse Management (EWM) module when the system is unable to find a handling unit (HU) that is required for a specific operation, such as picking, packing, or shipping. This error can arise due to various reasons, and understanding the cause is essential for resolving it.
  Causes:
  
  Missing Handling Unit: The handling unit that you are trying to work with does not exist in the system. This could be due to incorrect input or a handling unit that has not been created yet.
  Incorrect HU Status: The handling unit may exist but could be in a status that does not allow it to be used for the operation you are attempting (e.g., it might be marked as "blocked" or "not available").
  Data Inconsistency: There may be inconsistencies in the database or issues with the data synchronization between different modules or systems.
  Incorrect Warehouse Process: The process you are trying to execute may not be valid for the current warehouse configuration or the handling unit type.
  User Authorization: The user may not have the necessary permissions to access or manipulate the handling unit.
  
  Solutions:
  
  Verify Handling Unit Existence: Check if the handling unit you are trying to use actually exists in the system. You can do this by using transaction codes like /SCWM/HU to search for the handling unit.
  Check HU Status: If the handling unit exists, verify its status to ensure it is available for the operation you are trying to perform. You can check the status in the handling unit details.
  Create Handling Unit: If the handling unit does not exist, you may need to create it. This can be done through the appropriate transaction or process in EWM.
  Review Warehouse Processes: Ensure that the process you are trying to execute is valid for the handling unit and the warehouse configuration. Consult the warehouse process documentation if necessary.
  Check User Permissions: Ensure that the user has the necessary authorizations to access and manipulate handling units. If not, contact your system administrator to adjust the permissions.
  Consult Logs and Documentation: Check system logs for any additional error messages or warnings that might provide more context. Also, refer to SAP documentation for any specific notes related to this error.
