• What is the cause and solution for SAP error message VMP_MSG360 - BOM item &1 is marked as non-phantom assembly ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  VMP_MSG360: BOM item &1 is marked as non-phantom assembly
  
  Meaning / Cause:
  This error occurs during the processing of a Bill of Materials (BOM) when an item in the BOM is expected to be a phantom assembly, but it is actually marked as a non-phantom assembly in the system.
  
  Phantom Assembly: A phantom assembly is a special type of BOM item that is not stocked or produced as a separate item but is exploded directly into its components during production or planning. It simplifies the BOM structure by avoiding unnecessary production steps.
  The error indicates that the system expected the BOM item to be a phantom (usually because of the context, e.g., in a production order or planning run), but the item is flagged as a regular assembly (non-phantom).
  
  
  When does this error typically occur?
  
  During production order creation or material requirements planning (MRP) when the system tries to explode the BOM.
  When a BOM contains an item that is set as a phantom assembly in the BOM but the material master or item category does not correspond to a phantom assembly.
  When the BOM item category or the material master data is inconsistent with the expected phantom status.
  
  
  Solution:
  
  
  Check the BOM item category:
  
  Go to transaction CS02 (Change BOM) or CS03 (Display BOM).
  Check the item category of the BOM item &1.
  For phantom assemblies, the item category should be 'L' (phantom item).
  If it is not 'L', and the item is intended to be a phantom assembly, change the item category to 'L'.
  
  
  
  Check the material master settings:
  
  Go to transaction MM02 (Change Material Master).
  Check the MRP 3 view.
  Verify if the material is flagged as a phantom assembly (e.g., the "Phantom item" indicator).
  If the material is not intended to be a phantom, but the BOM expects it to be, correct the BOM or material master accordingly.
  
  
  
  Consistency between BOM and material master:
  
  Ensure that the BOM item category and the material master settings are consistent.
  If the BOM item is marked as phantom, the material master should support this usage.
  
  
  
  Adjust the BOM or material master as per business requirements:
  
  If the item should not be phantom, change the BOM item category to a regular assembly.
  If the item should be phantom, update the BOM item category and material master accordingly.
  
  
  
  
  Additional Information:
  
  Phantom assemblies are used to simplify production and planning by avoiding unnecessary production steps.
  Incorrect phantom settings can cause planning and production errors.
  Always coordinate changes with production planning and engineering teams to ensure BOM correctness.
