How To Fix VSCE408 - Class &1 is used in object dependency &3 but is never instantiated

SAP Error Message - Details

• Message type: E = Error

• Message class: VSCE - Messages for SCE

• Message number: 408

• Message text: Class &1 is used in object dependency &3 but is never instantiated

What causes this issue?

The specified object is used in dependencies. However, no instances of
the object have been created in a configuration for the current
knowledge base: It neither appears as an entry object for the
configuration in a knowledge base profile, nor in a bill of material.

System Response

The specified object is copied to the knowledge base runtime version,
but the corresponding dependency cannot be used during runtime. The
object and the referenced dependency are unnecessary uses of resources
(such as memory).

How to fix this error?

Check whether you can remove the relationship from the configuration
model.

• What is the cause and solution for SAP error message VSCE408 - Class &1 is used in object dependency &3 but is never instantiated ?

  The SAP error message VSCE408 indicates that a class (denoted as &1) is referenced in an object dependency (denoted as &3), but it has not been instantiated. This typically occurs in the context of variant configuration in SAP, where object dependencies are used to define rules and conditions for configurable products.
  Cause:
  
  Uninstantiated Class: The class mentioned in the error message is defined but has not been instantiated in the context of the object dependency. This means that while the system recognizes the class, it does not have an instance of it to work with.
  Incorrect Configuration: The object dependency may be incorrectly configured, leading to references to classes that are not properly instantiated.
  Missing Implementation: The class may not have the necessary implementation or methods that are expected to be called within the object dependency.
  
  Solution:
  
  
  Instantiate the Class: Ensure that the class is instantiated properly within the object dependency. You can do this by using the appropriate syntax to create an instance of the class in the object dependency.
  
  Example: Use the CREATE OBJECT statement in ABAP to instantiate the class.
  
  
  
  Check Object Dependency: Review the object dependency to ensure that it is correctly referencing the class. Make sure that the class is intended to be used in that context and that it has been defined correctly.
  
  
  Review Class Definition: Check the class definition to ensure that it is complete and that all necessary methods are implemented. If the class is abstract or has not been fully defined, it may lead to this error.
  
  
  Debugging: If the issue persists, consider debugging the object dependency to trace where the instantiation is expected and why it is not occurring.
  
  
  Documentation and Help: Refer to SAP documentation or help resources for more information on how to properly instantiate classes in object dependencies.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Variant Configuration: Familiarize yourself with the concepts of variant configuration, object dependencies, and class instantiation in SAP.
  ABAP Programming: If you are comfortable with ABAP, you can look into the code to see how classes are instantiated and used within the context of your specific application.
  
  By following these steps, you should be able to resolve the VSCE408 error and ensure that your object dependencies are functioning correctly.
