• What is the cause and solution for SAP error message TWBHS401 - Only select test cases from one logical component ?

  The SAP error message TWBHS401 indicates that you are trying to select test cases from multiple logical components in a test planning or execution scenario, which is not allowed. This error typically arises in the context of SAP Solution Manager, particularly when working with test management functionalities.
  Cause:
  The error occurs because the system enforces a rule that only allows the selection of test cases from a single logical component at a time. Logical components are used to define the scope of a system or application area, and mixing test cases from different logical components can lead to inconsistencies in test execution and reporting.
  Solution:
  To resolve the TWBHS401 error, you should follow these steps:
  
  
  Review Your Selection: Check the test cases you have selected. Ensure that all selected test cases belong to the same logical component.
  
  
  Filter by Logical Component: If you need to work with test cases from different logical components, you will need to perform separate selections for each logical component. This means you should execute your test planning or execution tasks one logical component at a time.
  
  
  Adjust Test Case Assignment: If you find that some test cases are incorrectly assigned to different logical components, you may need to reassign them to the correct logical component.
  
  
  Consult Documentation: Refer to the SAP Solution Manager documentation for more details on managing test cases and logical components. This can provide additional context and best practices.
  
  
  Seek Help from SAP Support: If you continue to experience issues or if the error seems to be occurring under normal circumstances, consider reaching out to SAP Support for further assistance.
