• What is the cause and solution for SAP error message SEDI_ADT002 - Navigation target undecidable: More than one implementation exists ?

  The SAP error message SEDI_ADT002 with the description "Navigation target undecidable: More than one implementation exists" typically occurs in the context of the ABAP Development Tools (ADT) when you are trying to navigate to a specific implementation of an interface or an abstract class, but there are multiple implementations available. This can happen in scenarios where:
  
  Multiple Implementations: There are multiple classes or methods that implement the same interface or abstract method, and the system cannot determine which one to navigate to.
  
  Cause
  The primary cause of this error is the existence of multiple concrete implementations for an interface or abstract class. When you attempt to navigate to the implementation, the system does not know which one to choose, leading to the "undecidable" navigation target.
  Solution
  To resolve this issue, you can take the following steps:
  
  
  Identify Implementations: Check the interface or abstract class you are trying to navigate from. Use the ABAP Development Tools to list all the concrete classes that implement the interface or extend the abstract class.
  
  
  Explicit Navigation: Instead of relying on the automatic navigation feature, manually navigate to the specific implementation you are interested in. You can do this by:
  
  Opening the class or method directly from the Object Navigator (SE80) or Class Builder (SE24).
  Using the "Where-Used List" (Ctrl + Shift + F3) to find all implementations and selecting the one you want.
  
  
  
  Refactor Code: If you have control over the codebase, consider refactoring the implementations to reduce ambiguity. This could involve:
  
  Renaming classes or methods to make their purpose clearer.
  Consolidating similar implementations if they serve the same purpose.
  
  
  
  Check for Inheritance: If the implementations are part of an inheritance hierarchy, ensure that you are aware of the class structure and how the methods are overridden.
  
  
  Consult Documentation: If you are working with standard SAP classes or interfaces, refer to the SAP documentation or help resources to understand the intended use of the implementations.
