Hello Simon,
can you check whether SAP KBA #1857366 - "No Switch to HTTPS occurred" describes what you need?
According to this KBA:
"Execute transaction code SICF -> navigate to the webdynpro ABAP node from the application you're facing the issue, then:
"Error Pages" tab -> "Logon Errors" -> "System Logon" radio button -> "Configuration" button.
In the "Actions During Logon" section, the dropdown box "Protocol" should have value "Logon via HTTPS".
1.If HTTPS/SSL is not needed, then the following two options are possible:
- Change the protocol to "Do Not Switch"
- Select "Do Not Display Warnings""
Of course, in this case the relevant (logon) application needs to be adjusted.
Best regards,
Laszlo
