• What is the cause and solution for SAP error message SABP_UNIT100 - The class pool <&1> contains no executable unit tests; see long text ?

  The SAP error message SABP_UNIT100 indicates that the specified class pool does not contain any executable unit tests. This message typically arises when you are trying to execute or run unit tests for a class pool, but there are no defined unit tests available.
  Cause:
  
  No Unit Tests Defined: The primary cause of this error is that the class pool specified does not have any unit tests implemented. Unit tests are typically written in ABAP using the ABAP Unit framework.
  Incorrect Class Pool: You may be trying to run tests on a class pool that is not intended for unit testing or does not contain the relevant test classes.
  Test Classes Not Active: The test classes may exist but are not active or properly configured.
  
  Solution:
  
  
  Create Unit Tests: If you are the developer, you need to create unit tests for the classes in the specified class pool. You can do this by:
  
  Navigating to the ABAP Editor (SE38 or SE80).
  Creating a new test class using the FOR TESTING addition in your class definition.
  Implementing test methods using the METHOD keyword and the TEST addition.
  
  Example:
  CLASS my_test_class DEFINITION FOR TESTING
    DURATION SHORT
    RISK LEVEL HARMLESS.
  ENDCLASS.
  
  CLASS my_test_class IMPLEMENTATION.
    METHOD test_my_method.
      " Your test code here
    ENDMETHOD.
  ENDCLASS.
  
  
  Check Class Pool: Ensure that you are referencing the correct class pool that is supposed to contain the unit tests. Verify the name and ensure it matches the intended class pool.
  
  
  Activate Test Classes: If the test classes are already defined, make sure they are activated. You can do this by checking the status of the class in the ABAP Workbench.
  
  
  Review Test Configuration: Ensure that the test classes are properly configured and that there are no syntax errors or other issues preventing them from being recognized as executable tests.
  
  
  Related Information:
