• What is the cause and solution for SAP error message 8B128 - Screen control not found ?

  The SAP error message 8B128: Screen control not found typically occurs when the system is unable to find the screen control that is being referenced in a program or transaction. This can happen for various reasons, including missing or incorrectly configured screen elements, issues with the program logic, or problems with the underlying data.
  Causes:
  
  Missing Screen Control: The screen control (e.g., a specific screen or field) that the program is trying to access does not exist in the system.
  Incorrect Program Logic: The program may be trying to call a screen that is not defined or is incorrectly referenced.
  Transport Issues: If the program or screen was recently transported from another system, it may not have been transported correctly, leading to missing elements.
  Authorization Issues: The user may not have the necessary authorizations to access the screen or transaction.
  Custom Development Issues: If the error arises from custom code, there may be bugs or misconfigurations in the custom development.
  
  Solutions:
  
  Check Screen Control Definition: Verify that the screen control being referenced exists in the system. You can do this by checking the screen number in the relevant transaction or program.
  Review Program Logic: Look at the ABAP code to ensure that the screen control is being called correctly. Check for any typos or incorrect references.
  Transport Check: If the issue arose after a transport, ensure that all necessary objects were included in the transport request and that they were imported correctly.
  Authorization Check: Ensure that the user has the necessary authorizations to access the screen or transaction. You can check this in transaction SU53 or by consulting with your security team.
  Debugging: If you have access to the ABAP debugger, you can set breakpoints in the program to see where the error occurs and gather more information about the state of the program at that point.
