Hi Ivan,
This statement in the documentation is incorrect - I have spoken to the SRM docu colleague and it will be changed in the next docu release.
In the meantime, the correct information is provided in our NWBC FAQs:
"In general SRM - including OBN - works with NWBC for Desktop or HTML. However, if you use SRM as an integration hub and then navigate to a remote system, then OBN will NOT work within the remote system.
See also SAP Note 2060102 for further limitations of NWBC for HTML.
You can also use SRM with the Portal Independent Navigation Frame, a client developed by the SRM group and based on - but not identical to - NWBC for HTML. See the Help Portal for more information: Portal-Independent Navigation Frame. "
Best wishes,
Julie.
