• What is the cause and solution for SAP error message /IWFND/CM_DESIGNTIME028 - Cannot delete BOP configuration as class &1 still exists ?

  The SAP error message /IWFND/CM_DESIGNTIME028 indicates that there is an attempt to delete a Business Object (BOP) configuration, but the deletion cannot proceed because a class associated with that configuration still exists. This typically occurs in the context of SAP Gateway and OData services, where BOP configurations are used to define the behavior of OData services.
  Cause:
  The error is caused by the existence of a class that is still linked to the BOP configuration you are trying to delete. This could happen if:
  
  The class is still being used in the system.
  There are dependencies or references to the class that prevent its deletion.
  The BOP configuration is not fully detached from the class.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Class: Check the error message for the specific class name (denoted by &1). This will help you identify which class is causing the issue.
  
  
  Check Dependencies: Investigate if there are any active references or dependencies related to the class. You can do this by:
  
  Using transaction codes like SE80 (Object Navigator) or SE11 (Data Dictionary) to find where the class is being used.
  Checking for any OData services that might be utilizing the class.
  
  
  
  Remove References: If you find that the class is being used in any active OData services or other configurations, you will need to:
  
  Remove or deactivate those references.
  Ensure that the class is not being used in any active implementations.
  
  
  
  Delete the Class: Once you have confirmed that the class is no longer in use, you can delete the class using transaction SE24 (Class Builder).
  
  
  Retry Deletion of BOP Configuration: After successfully deleting the class, attempt to delete the BOP configuration again.
  
  
  Check for Transport Requests: If the changes are part of a transport request, ensure that the transport is released and that there are no pending requests that might be causing the issue.
