Business Client (any Version) and NW 7.52 not working L (IE11 Quirk Mode ) ?

Since we upgraded our System to NW 7.52, access with SAP Business Client does no longer work - I get a Dump UNCAUGHT_EXCEPTION CX_UR_NOT_SUPPORTED_DEVICE CLUR_NW7 _SERVER===============CP in the Backend every time I try it.

A comment in the dumping code says
* Quirks mode not longer supported (Release 7.52 SP0 and higher)

* Note 0001672817

So, what to do? Of course, I want to keep my high backend release (NW7.52) but of course I'd also like to use my modern Frontend-Client (BC6.5).

As far as I found out so far, I can’t simply force IE not use "Quirk Mode" and thus have things working again...

Important: This is about the "Business Client" connection type.

I also opend an incident with SAP (528771 / 2017) for this, but noone seems to care :-(

this is kind of frustrating :-(

I just had a quick look to the support portal, but this note looks like is addressing your issue?

Thanks a lot, sound's very promissing, especially as it leads me to:

2561531 - WDA: Exception CX_UR_NOT_SUPPORTED_DEVICE in class CLUR_NW7_SERVER. Wrong default rendering mode (Version 1 from 10.11.2017 in English)

I'll try it and keep you updated!


Perfect! Note 2283316 solved it !

All good now!

Thanks a lot, Bartosz!


PS: just for the record: that note was created 10.11.2017 - I raised the issue on 02.11.2017 allready -> so I'n not guilty of "failed to search"! :-)


Great, thanks for letting us know :)

I almost didn't post the reply, because when I saw the search results I thought "Oh, he has definitely seen it!" :P

Best regards
