SAP GUI HTML / Browser control use F12 Development tools

[tilo-sap]

How to get the F12 browser dev tools open for SAP GUI HTML Browser control?

Works for SAP GUI HTML / Browser control via Edge (based on Chromium) so WebView2. 

Create these Win Registry Keys either manual

Path:  Computer\HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\WebView2\AdditionalBrowserArguments

Name: saplogon.exe
Value "--auto-open-devtools-for-tabs"

or via admin powershell

New-Item 'HKCU:\Software\Policies\Microsoft\Edge\WebView2\AdditionalBrowserArguments' -Force | `
 New-ItemProperty -Name saplogon.exe -Value "--auto-open-devtools-for-tabs" -Force

I needed it to debug some cookie issue.

btw the user dir and cookies folder is here:

"C:\Users\tsoadmin\AppData\Local\SAP\SAP GUI\EdgeUserData\EdgeUserDataSystemAware\EBWebView\Default\Network\Cookies" (SQL lite DB) but chrome has exclusive lock on the file so can't be read while open.

Here the full cmd of a running WebView2 instance.

"C:\Program Files (x86)\Microsoft\EdgeWebView\Application\127.0.2651.105\msedgewebview2.exe" --embedded-browser-webview=1 --webview-exe-name=saplogon.exe --webview-exe-version="800 Final Release - 64bit" --user-data-dir="C:\Users\tsoadmin\AppData\Local\SAP\SAP GUI\EdgeUserData\EdgeUserDataSystemAware\EBWebView" --noerrdialogs --embedded-browser-webview-dpi-awareness=1 --edge-webview-custom-scheme=sap-cust,1,1,sapevent,1,1,saphtmlp,1,1,sapr3,1,1 --enable-features=MojoIpcz,msSingleSignOnOSForPrimaryAccountIsShared --mojo-named-platform-channel-pipe=9484.10484.18364521422129778599
