• What is the cause and solution for SAP error message ABAP_TESTDOUBLE028 - &4 Illegal configuration for &1. Static methods not supported ?

  The SAP error message ABAP_TESTDOUBLE028 indicates that there is an illegal configuration for a specific object, and it specifically mentions that static methods are not supported. This error typically arises in the context of unit testing in ABAP, particularly when using test doubles (mocks or stubs) in your tests.
  
  Cause:
  The error occurs when you attempt to create a test double (like a mock or stub) for a class that contains static methods. In ABAP, the test double framework does not support mocking or stubbing static methods because they are not tied to an instance of a class. This limitation is inherent to the way static methods are designed in object-oriented programming, as they belong to the class itself rather than to any instance of the class.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Refactor the Code: If possible, refactor the code to avoid using static methods. Instead, use instance methods
