• What is the cause and solution for SAP error message VMP_MSG352 - Manufacturing substitute is assigned; component cannot be marked phantom ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  VMP_MSG352: Manufacturing substitute is assigned; component cannot be marked phantom
  
  Cause:
  This error occurs when you try to mark a component in a Bill of Materials (BOM) as a phantom item, but the system detects that the component has a manufacturing substitute assigned to it.
  
  Phantom item: A phantom item is a non-stocked item used in production to simplify BOM structure. It is not produced or stocked but is exploded during production.
  Manufacturing substitute: This is an alternative component that can be used in manufacturing instead of the original component.
  
  SAP does not allow a component to be marked as phantom if it has a manufacturing substitute assigned because the substitute logic conflicts with the phantom item concept.
  
  Explanation:
  
  When a component has a manufacturing substitute, SAP expects the component to be managed explicitly in production.
  Marking it as phantom means it should be exploded and not managed as a separate item.
  These two concepts are contradictory, so SAP prevents this to avoid inconsistencies in production planning and execution.
  
  
  Solution:
  To resolve this error, you have the following options:
  
  
  Remove the manufacturing substitute assignment for the component if you want to mark it as phantom.
  
  Go to transaction CS02 (Change BOM) or the relevant transaction where the substitute is assigned.
  Remove the manufacturing substitute for the component.
  Then mark the component as phantom.
  
  
  
  Do not mark the component as phantom if the manufacturing substitute is required.
  
  Keep the component as a normal item in the BOM.
  Use the manufacturing substitute functionality as intended.
  
  
  
  Review BOM design:
  
  Evaluate whether the component should be phantom or have substitutes.
  Adjust the BOM structure accordingly to align with production requirements.
