• What is the cause and solution for SAP error message CPCL_VERS103 - Parameter effectivity is used. You can only assign one MBOM ?

  The SAP error message CPCL_VERS103 indicates that there is an issue with the assignment of a Manufacturing Bill of Materials (MBOM) when parameter effectivity is being used. This error typically arises in the context of production planning and control, particularly when dealing with variant configuration or when managing multiple versions of a product.
  Cause:
  The error occurs because:
  
  Parameter Effectivity: When parameter effectivity is activated, it restricts the assignment of multiple MBOMs to a single material. This means that only one MBOM can be assigned to a material for a specific configuration or variant.
  Multiple Assignments: If there are attempts to assign more than one MBOM to a material that is configured with parameter effectivity, SAP will throw this error.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check MBOM Assignments:
  
  Go to the relevant transaction (e.g., CS02 for changing BOMs) and check the current assignments of MBOMs to the material in question.
  Ensure that only one MBOM is assigned for the specific configuration or variant.
  
  
  
  Review Configuration Settings:
  
  If you need to use multiple MBOMs, consider whether parameter effectivity is necessary for your scenario. If it is not required, you may disable it.
  If you need to keep parameter effectivity, ensure that your design allows for only one MBOM per configuration.
  
  
  
  Adjust BOMs:
  
  If you have multiple MBOMs that need to be used, consider consolidating them into a single MBOM or using alternative methods to manage the variants without conflicting with the parameter effectivity.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to MBOMs and parameter effectivity for more detailed guidance on best practices and configurations.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists or if you are unsure about making changes, consider reaching out to SAP support or your internal SAP team for assistance.
  
  
  
  Related Information:
  
  MBOM (Manufacturing Bill of Materials): A detailed list of components and materials needed to manufacture a product, including their quantities and relationships.
  Parameter Effectivity: A feature in SAP that allows for the management of different product configurations based on specific parameters, often used in variant configuration scenarios.
  Transactions: Familiarize yourself with relevant SAP transactions such as CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM) for managing BOMs.
  
  By following these steps, you should be able to resolve the CPCL_VERS103 error and ensure that your MBOM assignments are correctly configured.
