• What is the cause and solution for SAP error message MPE_RTG_UI228 - Do not assign BOM items without object dependencies to logical components ?

  The SAP error message MPE_RTG_UI228 indicates that there is an issue with assigning Bill of Materials (BOM) items to logical components when those BOM items do not have object dependencies. This error typically arises in the context of SAP's Variant Configuration (VC) or when working with configurable materials.
  Cause:
  The error occurs because the system expects BOM items to have object dependencies defined when they are assigned to logical components. Object dependencies are rules or conditions that determine how components are selected or configured based on the characteristics of the product. If a BOM item lacks these dependencies, the system cannot determine how to handle it in the context of the logical component, leading to this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check BOM Items: Review the BOM items that you are trying to assign to the logical components. Ensure that each item has the necessary object dependencies defined.
  
  
  Define Object Dependencies:
  
  If any BOM items are missing object dependencies, you will need to create them. This can be done in the SAP system using transaction codes such as:
  
  CU01: Create Object Dependency
  CU02: Change Object Dependency
  CU03: Display Object Dependency
  
  
  Define the necessary dependencies that relate to the characteristics of the configurable material.
  
  
  
  Review Logical Components: Ensure that the logical components themselves are correctly defined and that they are set up to work with the BOM items you are trying to assign.
  
  
  Reassign BOM Items: After ensuring that all BOM items have the required object dependencies, attempt to reassign them to the logical components.
  
  
  Testing: After making the necessary changes, test the configuration to ensure that the error does not reoccur.
  
  
  Related Information:
  
  Object Dependencies: These are crucial in variant configuration as they help in determining which components are relevant based on the selected characteristics of a product.
  BOM and Configuration: Understanding how BOMs and configurations work in SAP is essential for managing complex products that have multiple variants.
  SAP Documentation: Refer to SAP Help documentation for detailed guidance on managing BOMs and object dependencies in the context of variant configuration.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP Notes for any specific patches or updates related to this error message.
