Hello everybody,

I followed Jocelyn Blogpost

Leading S/4HANA UX – Notification Center – Part 1 – Activation

for a SAP NetWaever with this configuration

SAP_ABA 750 5 SAPK-75005INSAPABA Cross-Application Component

SAP_BASIS 750 5 SAPK-75005INSAPBASIS SAP Basis Component

SAP_BW 750 5 SAPK-75005INSAPBW SAP Business Warehouse

SAP_GWFND 750 5 SAPK-75005INSAPGWFND SAP Gateway Foundation

SAP_UI 751 0 - User Interface Technology SAPUIFT 100 1 SAPK-10001INSAPUIFT

SAP UI Frontend Implementation Technolog ST-PI 740 5 SAPK-74005INSTPI

SAP Solution Tools Plug-In UIBAS001 200 0 - UI for Basis Applications 1.0

which our System-Admin set up me for testing purposes.

The outcome of every step was already there or activated. Only for the last step

Activate the ABAP Push Channel

I got the error message SAP_WEBSOCKET does not exist in /IWNGW/NPUSHR.

But when I run /IWNGW/BEP_DEMO to send a demonstration notification, it works.

Is there something new or different on my system, so that SAP_WEBSOCKET is not used?

Best regards,

Christian.

Hi Christian,

I have the same problem, but this one is when I'm supposed to maintain and activate Push Channels. The mentioned table /IWNGW/NPUSHR can be maintained through maintenance view, but I'm not sure what entry needs to be maintained for the class etc.

Regarding the entry missing, there is a maintenance view with name /IWNGW/VNPUSHR for this table.

SAP_SMP /IWNGW/CL_OUT_NOTIF_SMP SMP push channel
SAP_WEBSOCKET /IWNGW/CL_OUT_NF_WS_AGENT WebSocket push channel
