DSM: XHR Status was 500 not able to deliver PRO54-DSM data

Hi,

I am trying to use NWBC for HTML. We use ERP60 with EHP6 (NW 7.31)

When I started transaction /nwbc, Internet Explorer (Version 8.0.60001....) starts.

But every time I click a link I get a small error popup--> "DSM: XHR Status was 500 not able to deliver PRO54-DSM data."

Therefore I started to implement every SP concerning NWBC I could find. The main focus was PLMWUI.

My latest queue was:

-------------------------------------

SAPKB73109

SAPKA73109

SAPK-73109INPIBASIS

SAPKW73109

SAPKNA7030

SAPK-73109INWEBCUIF

SAPK-73109INSAPBSFND

SAPKH60609

SAPK-40606INEAIPPE

SAPK-60609INEAAPPL

SAPK-70209INPLMWUI

------------------------------------------

After that I had to implement following notes:

0001883635 SAP-NWBC-ABAP-Laufzeit-Patch 32

0001908112 SAP NWBC ABAP Runtime Patch 33

BUT I still get the same error message. Does anyone have an idea???
