VSCE405
- Class & cannot have a BOM ?The SAP error message VSCE405 indicates that a class cannot have a Bill of Materials (BOM) associated with it. This error typically arises in the context of SAP's Variant Configuration (VC) when trying to assign a BOM to a class that is not allowed to have one.
Cause:
- Class Type: The class you are trying to associate with a BOM is likely defined as a "class type" that does not support BOMs. In SAP, certain class types are designated for specific purposes, and not all of them can have BOMs.
- Configuration Settings: The configuration settings for the class may not allow for BOM assignment. This could be due to the way the class was set up in the system.
- Incorrect Assignment: You may be attempting to assign a BOM to a class that is intended for use with characteristics and variants, rather than physical components.
Solution:
- Check Class Type: Verify the class type of the class you are working with. You can do this by navigating to the class in the SAP system and checking its properties. Ensure that it is a class type that supports BOMs (typically class type 300 for material classes).
- Use Appropriate Class: If the class type does not support BOMs, consider using a different class type that does. For example, if you need to manage a BOM, you might need to create a material master record instead of using a class.
- Review Configuration: Check the configuration settings for the class. Ensure that it is set up correctly to allow for BOM assignments if applicable.
- Consult Documentation: Refer to SAP documentation or help resources for more information on class types and their capabilities regarding BOMs.
