• What is the cause and solution for SAP error message 29856 - Object dependencies only supported for configurable BOMs ?

  The SAP error message 29856, "Object dependencies only supported for configurable BOMs," typically occurs when you are trying to use object dependencies in a Bill of Materials (BOM) that is not configured as a configurable BOM. Here’s a breakdown of the cause, solution, and related information for this error:
  Cause:
  
  
  Non-configurable BOM: The error arises when you attempt to assign object dependencies (like selection conditions or alternative items) to a BOM that is not defined as a configurable BOM. Object dependencies are only applicable to configurable BOMs, which are used in scenarios where products can be customized based on specific options or features.
  
  
  Incorrect BOM Type: The BOM type you are using may not support object dependencies. For example, standard BOMs or production BOMs do not support the use of object dependencies.
  
  
  Solution:
  
  
  Convert to Configurable BOM: If you need to use object dependencies, you should convert your BOM to a configurable BOM. This involves:
  
  Creating a new configurable BOM or modifying the existing BOM to include configuration settings.
  Ensure that the material master for the BOM item is set up as a configurable material.
  
  
  
  Check BOM Type: Verify the type of BOM you are working with. If it is not a configurable BOM, you may need to create a new BOM with the correct type.
  
  
  Review Object Dependencies: If you are not intending to use object dependencies, review your configuration to ensure that you are not mistakenly trying to assign them to a non-configurable BOM.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for detailed steps on how to create and manage configurable BOMs and object dependencies.
  
  
  Related Information:
  
  Configurable BOM: A configurable BOM allows for the creation of products that can be customized based on customer requirements. It uses characteristics and values to define the options available.
  Object Dependencies: These are rules that determine how components of a configurable product are selected based on the characteristics chosen during configuration.
  SAP Notes and Support: Check SAP Notes for any specific patches or updates related to this error message. SAP Support can also provide assistance if you encounter issues that are not resolved through standard procedures.
  
  Additional Steps:
  
  Testing: After making changes, test the configuration to ensure that the BOM behaves as expected and that the error does not reoccur.
  Training: If you are frequently working with configurable BOMs, consider training sessions to better understand the configuration process and the use of object dependencies.
  
  By following these steps, you should be able to resolve the error message 29856 and effectively manage your BOMs in SAP.
