• What is the cause and solution for SAP error message CNV_DMC_UI_FW_EXCEPT034 - Error when creating object; type &1 is an abstract type ?

  The SAP error message CNV_DMC_UI_FW_EXCEPT034 typically indicates that there is an issue related to the creation of an object in the Data Migration Cockpit (DMC) framework. The specific part of the message stating "type &1 is an abstract type" suggests that the system is trying to instantiate an abstract class or type, which cannot be done directly.
  Cause:
  
  Abstract Type: In object-oriented programming, an abstract type (or class) is a class that cannot be instantiated on its own. It is meant to be subclassed, and only its concrete subclasses can be instantiated. If the system is trying to create an instance of an abstract type, it will throw this error.
  Configuration Issues: There may be a misconfiguration in the DMC settings or the specific migration object you are trying to create.
  Missing Implementation: The required concrete implementation for the abstract type may not be available or properly defined in the system.
  
  Solution:
  
  Check Object Type: Verify the type of object you are trying to create. Ensure that you are not attempting to instantiate an abstract class directly. Instead, you should be using a concrete subclass that implements the necessary functionality.
  Review Configuration: Go through the configuration settings in the Data Migration Cockpit to ensure that everything is set up correctly. Look for any missing or incorrect settings that might lead to this error.
  Consult Documentation: Refer to the SAP documentation for the Data Migration Cockpit to understand the expected object types and their relationships. This can help you identify if you are using the correct types.
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as this might resolve any underlying issues related to the DMC framework.
  Debugging: If you have access to the development environment, you can debug the code to see where the instantiation is failing and identify the abstract type being referenced.
