Breakpoint in Eclipse not hit when triggering an action from UI5

Hello SAP Experts,

I want to debug a BOPF authorisation class in Eclipse when a corresponding CUD operation is triggered from an SAP Fiori Application. I have set the breakpoint in Eclipse in the corresponding BOPF authorisation class, but when I trigger the operation from UI, the breakpoint in Eclipse is not hit. Could you please tell me what should I check in order to enable that? If I set an external breakpoint in SE80, than it is working.

System Requirements which I have:

1. Eclipse Oxygen with ADT 2.83.1

2. SAP Netweaver 7.52 with SAP S/4HANA 1709

Thanks in advance for your support,

    Hi Chiuaru,

    there is a known issue in UI5 that makes UI5 requests undebuggable for the ADT Debugger. What UI5 version are you using? You can find that out via Ctrl-Alt-Shift-P in the app / launchpad.

    Correction comes with the following UI5 versions:

    • Hi Catalin,

      I'm not an expert for shipment / versioning of UI5 so I had to ask some colleagues and the following is without any warranty:

      It seems that UI5 1.48.1 is delivered with software component SAP_UI 7.52 SP0 which is delivered with NetWeaver 7.52 SP0. Since you currently have UI5 1.48.1 I assume that your frontend server already has software component SAP_UI 7.52 SP0 installed.

      In this case note 2468634 should most probably be relevant for your situation.

      Best regards,

    Do other types of external breakpoints work? Try with a Web Dynpro app.

    If that doesn't work it could be a networking / firewall / port issue.
