  SAP Error Message:
  VMP_MSG343: Planning phantom assembly for shop floor BOM not possible
  
  Cause:
  This error occurs when the system tries to plan a phantom assembly (a non-stocked, transient assembly used to simplify BOM structures) but the Bill of Materials (BOM) for that phantom assembly is defined as a shop floor BOM (also called a production BOM or routing BOM). 
  In SAP, phantom assemblies are typically planned using sales BOMs or production BOMs without routing, but shop floor BOMs are specifically designed for detailed production planning and execution, including routing and work centers.
  The system does not allow planning of phantom assemblies if the BOM is a shop floor BOM because shop floor BOMs are intended for discrete production orders and detailed shop floor control, not for phantom assemblies which are exploded during planning.
  
  Explanation:
  
  Phantom Assembly: A BOM item flagged as a phantom item is not produced or stocked but is exploded during planning to its components.
  Shop Floor BOM: A BOM used in production orders with routing and detailed shop floor control.
  Planning phantom assemblies requires BOMs that are not shop floor BOMs.
  
  
  Solution:
  
  
  Check the BOM Usage:
  
  Go to transaction CS03 (Display BOM).
  Enter the material and BOM usage.
  Verify if the BOM is flagged as a shop floor BOM (usually BOM usage 2 or 3).
  
  
  
  Change BOM Usage or BOM Type:
  
  If the BOM is a shop floor BOM, and you want to use it for phantom assembly planning, you need to:
  
  Create a separate BOM with usage suitable for phantom assemblies (e.g., usage 1 for production BOM without routing).
  Or remove the shop floor BOM flag if appropriate (not recommended if shop floor control is needed).
  
  
  
  
  
  Adjust Phantom Assembly Flag:
  
  Check if the material is flagged as a phantom assembly in the BOM item.
  Phantom assemblies should be planned only with BOMs that are not shop floor BOMs.
  
  
  
  Use Appropriate Planning Strategy:
  
  Phantom assemblies are typically used in make-to-stock or make-to-order scenarios without detailed shop floor control.
  For detailed production with shop floor BOMs, consider using discrete production orders without phantom assemblies.
  
  
  
  Consult with Production Planning Team:
  
  Align BOM and routing setup with production planning requirements.
  Ensure BOMs and routings are consistent with the production process.

  SAP Notes and Documentation:
  
  SAP Note related to phantom assemblies and BOM usage.
  SAP Help Portal on BOM and phantom assemblies.
  SAP PP (Production Planning) documentation on BOM types and planning.
  
  
  
  Key Concepts:
  
  Phantom assemblies are exploded during planning to simplify BOM structures.
  Shop floor BOMs are used for detailed production execution and require routings.
  Mixing phantom assemblies with shop floor BOMs is not supported.
  
  
  
  
  Summary:
  
  Cause: Phantom assembly planning attempted with a shop floor BOM.
  Solution: Use a BOM that is not a shop floor BOM for phantom assemblies or adjust BOM usage accordingly.
  Check: BOM usage, phantom assembly flag, and production planning strategy.
  
  
  If you need help with specific transactions or further troubleshooting, please provide details about the material, BOM usage, and planning scenario.
