• What is the cause and solution for SAP error message PT_TMW_FLD_SEL_CUST014 - &2 is a class, not an interface ?

  The SAP error message PT_TMW_FLD_SEL_CUST014 indicates that there is an issue related to the use of a class instead of an interface in the context of a specific operation or configuration. This error typically arises in the context of ABAP programming or when configuring certain functionalities in SAP systems.
  Cause:
  The error message states that &2 is a class, not an interface. This usually means that the system is expecting an interface type but has been provided with a class type instead. This can occur in various scenarios, such as:
  
  Incorrect Type Declaration: In your code or configuration, you may have declared a variable or parameter as a class type when it should be an interface type.
  Implementation Issues: If you are implementing a method or a function that requires an interface, but you are using a class that does not implement that interface, this error will occur.
  Configuration Errors: In some cases, this error can arise from incorrect configuration settings in the SAP system, where a class is mistakenly set up in a place where an interface is expected.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Code: Review the ABAP code where the error is occurring. Look for any declarations or parameters that are expected to be of an interface type and ensure that you are not using a class type instead.
  
  
  Use the Correct Type: If you find that a class is being used where an interface is required, change the type to the appropriate interface. Ensure that the class implements the required interface if necessary.
  
  
  Review Implementations: If you are implementing a method from an interface, ensure that the class you are using implements that interface correctly.
  
  
  Debugging: Use the ABAP debugger to trace the execution and identify where the type mismatch is occurring. This can help you pinpoint the exact location of the error.
  
  
  Consult Documentation: Refer to SAP documentation or the relevant development guidelines to understand the expected types for the specific functionality you are working with.
  
  
  Check Configuration: If the error is related to configuration settings, review the configuration to ensure that the correct types are being used.
