• What is the cause and solution for SAP error message RM228 - Phantom assembly & must not be bulk material ?

  The SAP error message RM228, which states "Phantom assembly & must not be bulk material," typically occurs in the context of production planning and material management within SAP. This error is related to the use of phantom assemblies in the bill of materials (BOM) and indicates that there is a configuration issue with the material type being used.
  Cause:
  
  Phantom Assembly Definition: A phantom assembly is a type of assembly that is not physically stocked but is used in the BOM for planning purposes. It is typically used to simplify the BOM structure.
  Material Type: The error suggests that the material in question is defined as a bulk material (e.g., raw materials that are not managed in discrete units) but is being treated as a phantom assembly. Phantom assemblies should not be defined as bulk materials in SAP.
  BOM Configuration: The BOM may have been incorrectly configured, where a bulk material is mistakenly set up as a phantom assembly.
  
  Solution:
  
  Check Material Type: Verify the material type of the item causing the error. Ensure that it is not set as a bulk material if it is intended to be a phantom assembly. You can do this by checking the material master data in transaction MM03.
  Change Material Type: If the material is incorrectly classified, you may need to change its material type to a suitable one that allows it to be used as a phantom assembly (e.g., finished goods or semi-finished goods).
  Review BOM Configuration: Check the BOM configuration for the phantom assembly. Ensure that the components and the assembly itself are correctly defined and that the phantom assembly is not linked to bulk materials.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on configuring phantom assemblies and material types.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like MM03 (Display Material), CS03 (Display BOM), and CS02 (Change BOM) to review and modify material and BOM configurations.
  Material Master: Understanding the material master data and its settings is crucial for resolving this error.
  Phantom Assemblies in SAP: Familiarize yourself with how phantom assemblies are used in SAP, including their benefits and limitations in production planning.
  
  If the issue persists after checking the above points, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in material management and production planning.
