• What is the cause and solution for SAP error message /PM0/3FWTG_GENERATOR312 - Error: Tried to set interface method &1. Interface not implemented ?

  The SAP error message /PM0/3FWTG_GENERATOR312 indicates that there is an attempt to call an interface method that has not been implemented in the relevant class or object. This typically occurs in the context of ABAP programming when an interface is defined, but the implementing class does not provide the necessary method definitions.
  Cause:
  
  Missing Implementation: The class that is supposed to implement the interface does not have the required method implemented.
  Incorrect Interface Assignment: The object being used may not be of the correct type or may not have the interface assigned properly.
  Version Mismatch: If there are changes in the interface (like adding new methods) and the implementing class has not been updated accordingly, this error can occur.
  Typographical Errors: There might be a typo in the method name or signature when trying to call the method.
  
  Solution:
  
  
  Check Interface Implementation:
  
  Go to the class that is supposed to implement the interface and ensure that all methods defined in the interface are implemented correctly.
  Use transaction SE80 or SE24 to navigate to the class and check its methods.
  
  
  
  Update Class:
  
  If the interface has been modified (e.g., new methods added), update the implementing class to include the new methods.
  
  
  
  Verify Object Type:
  
  Ensure that the object you are working with is indeed an instance of the class that implements the interface. You can use the TYPE statement or IS INSTANCE OF check in ABAP to verify this.
  
  
  
  Check for Typos:
  
  Review the method call for any typographical errors in the method name or parameters.
  
  
  
  Recompile:
  
  After making changes, recompile the class and any dependent objects to ensure that the changes take effect.
  
  
  
  Debugging:
  
  If the issue persists, use the ABAP debugger to trace the execution and identify where the error occurs. This can provide insights into the state of the objects and their types at runtime.
  
  
  
  Related Information:
  
  Transaction Codes: Use SE80 (Object Navigator) or SE24 (Class Builder) to manage classes and interfaces.
  Documentation: Review the SAP documentation for interfaces and classes to understand the requirements for implementing interfaces.
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide additional guidance related to this error message.
