• What is the cause and solution for SAP error message VMP_MSG228 - Configurable material under a non-configurable assembely is not allowed ?

  The SAP error message VMP_MSG228 indicates that there is an issue with the configuration of materials in a sales order or production order. Specifically, it states that a configurable material is being used under a non-configurable assembly, which is not allowed in the system.
  Cause:
  The error typically arises in the following scenarios:
  
  
  Incorrect BOM Structure: The Bill of Materials (BOM) for the non-configurable assembly is incorrectly set up to include a configurable material. In SAP, configurable materials (often referred to as variant materials) are designed to allow for customization based on specific characteristics, while non-configurable materials are fixed in their specifications.
  
  
  Sales Order Configuration: When creating a sales order, if a configurable material is mistakenly assigned to a non-configurable assembly, the system will throw this error.
  
  
  Master Data Issues: There may be issues with the master data setup for the materials involved, such as incorrect material types or BOM settings.
  
  
  Solution:
  To resolve the error, consider the following steps:
  
  
  Review BOM Configuration:
  
  Check the BOM for the non-configurable assembly to ensure that it does not include any configurable materials. If it does, you will need to either remove the configurable material or change the assembly to a configurable one if that aligns with your business requirements.
  
  
  
  Check Material Master Data:
  
  Verify the material master records for both the configurable and non-configurable materials. Ensure that the material types and settings are appropriate for their intended use.
  
  
  
  Adjust Sales Order:
  
  If the error occurs during sales order processing, review the items in the order. Ensure that you are not trying to include a configurable material under a non-configurable assembly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for guidance on configuring materials and BOMs correctly. This can provide insights into best practices and common pitfalls.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the changes in a development or quality environment before applying them to production to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Material Types: Understand the differences between configurable and non-configurable materials in SAP. Configurable materials are typically used in scenarios where customization is required, while non-configurable materials are standard products.
  BOM Types: Familiarize yourself with different types of BOMs (e.g., single-level, multi-level) and how they relate to configurable and non-configurable materials.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling configurable materials.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in materials management and sales order processing.
