  SAP Error Message:
  
  WS_TOOL135 Error when calling browser
  
  Cause:
  The error WS_TOOL135 typically occurs when SAP GUI tries to launch a web browser (for example, to open a URL or a web-based tool) but fails. This failure can be due to several reasons:
  
  The default web browser is not properly configured or is missing on the client machine.
  The browser executable path is incorrect or the browser is not installed.
  Security settings or restrictions prevent SAP GUI from launching the browser.
  Environment variables or registry entries related to the browser are corrupted or missing.
  SAP GUI or the system is unable to find the browser executable due to system path issues.
  
  
  Solution:
  To resolve the WS_TOOL135 error, you can try the following steps:
  
  
  Check Default Browser Settings:
  
  Ensure that a default web browser is set on the client machine.
  Open any URL outside SAP to verify the browser launches correctly.
  
  
  
  Verify Browser Installation:
  
  Confirm that the browser (e.g., Internet Explorer, Edge, Chrome, Firefox) is installed and working properly.
  If the browser was recently uninstalled or updated, reinstall or repair it.
  
  
  
  Check SAP GUI Configuration:
  
  In SAP GUI, go to Options ? Interaction Design ? Web Browser.
  Verify if the option "Use external web browser" is selected.
  If a specific browser path is set, ensure it points to the correct executable.
  
  
  
  Check Environment Variables and Registry:
  
  On Windows, check the registry keys related to the default browser:
  
  HKEY_CLASSES_ROOT\http\shell\open\command
  HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice
  
  
  Ensure these keys point to a valid browser executable.
  Check the PATH environment variable to ensure it includes the directory of the browser executable if needed.
  
  
  
  Test Browser Launch from Command Line:
  
  Try launching the browser manually from the command prompt using the same command SAP GUI would use.
  For example: start chrome.exe or start iexplore.exe
  
  
  
  Update or Reinstall SAP GUI:
  
  Sometimes, SAP GUI components related to browser integration may be corrupted.
  Reinstall or update SAP GUI to the latest version.
  
  
  
  Check Security Software:
  
  Some antivirus or security software may block SAP GUI from launching external applications.
  Temporarily disable or configure exceptions for SAP GUI.
  
  
  
  SAP Notes and Support:
  
  Check SAP Notes for any known issues related to WS_TOOL135.
