• What is the cause and solution for SAP error message /IBX/PE_CON_SRV020 - Connector class &1 is an abstact class ?

  The SAP error message /IBX/PE_CON_SRV020 Connector class &1 is an abstract class typically indicates that the system is trying to instantiate an abstract class, which is not allowed in object-oriented programming. An abstract class is a class that cannot be instantiated on its own and is meant to be subclassed by other classes that implement its abstract methods.
  Cause:
  
  Incorrect Configuration: The error may arise if the configuration is pointing to an abstract class instead of a concrete implementation.
  Missing Implementation: There may be a missing or incorrect implementation of the required class that should extend the abstract class.
  Code Issues: If custom code is involved, it may be trying to create an instance of the abstract class directly.
  
  Solution:
  
  Check Configuration: Review the configuration settings in the relevant transaction (e.g., SPRO) to ensure that the correct concrete class is specified instead of the abstract class.
  Implement Concrete Class: If you have access to the source code, ensure that there is a concrete class that extends the abstract class and implements all required methods.
  Debugging: If the error occurs in custom code, use debugging tools to trace where the instantiation is happening and correct it to use a concrete class.
  Consult Documentation: Refer to the SAP documentation or the specific module documentation to understand the expected classes and their relationships.
