  Cause:
  The error can occur due to several reasons, including:
  
  Hierarchy Issues: The assembly you are trying to move may have subassemblies that are not allowed to be moved together due to their status or configuration in the system.
  Stock Type Restrictions: The stock type of the assembly or subassemblies may not permit them to be moved together. For example, if one is in a restricted stock type (like blocked stock) and the other is in unrestricted stock.
  Open Production Orders: If there are open production orders for the assembly or its subassemblies, it may prevent the movement.
  Configuration Settings: The system configuration may not allow the movement of assemblies with their subassemblies due to specific business rules or settings.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Assembly and Subassembly Status: Ensure that both the assembly and its subassemblies are in a status that allows them to be moved. You may need to check their stock types and ensure they are not blocked or restricted.
  
  
  Review Open Production Orders: Check if there are any open production orders related to the assembly or subassemblies. If there are, you may need to complete or cancel those orders before attempting the move.
  
  
  Consult Configuration Settings: Review the configuration settings in the SAP system related to assembly movements. This may involve checking the movement types and any associated rules that govern how assemblies and subassemblies can be moved.
  
  
  Use Alternative Movement Methods: If the system does not allow the movement of assemblies with their subassemblies together, consider moving them separately. Move the assembly first, and then move the subassemblies afterward.
  
  
  Consult Documentation or Support: If the issue persists, consult SAP documentation or reach out to your SAP support team for further assistance. They may provide insights specific to your system configuration or business processes.
