Fiori app error - /IWBEP/CX_MGW_BUSI_EXCEPTION - Http request failed400

[former_member595020]

Dear All,

I am implementing a Fiori app, i.e. a transactional app which is delivered by SAP and I get in the app a message “error while saving the request: wrong assignment data”, (/IWBEP/CX_MGW_BUSI_EXCEPTION). In /IWBEP/ERROR_LOG and also the application log I can find different errors. Following messages I can see:

Http request failed40

/IWBEP/CX_MGW_BUSI_EXCEPTION

/IWBEP/CM_MGW_RT/022
/IWBEP/CM_MGW_RT022
Exception of type /IWFND/CX_SODATA: in the context of data services an unknown http error occurred

Exception of type /IWCOR/CX_DS_BAD_REQUEST: The data services request could not be understood due to malformed syntax.

Please find more details in the screenshot.

There’s no shortdump and it seems no authorization are missing. Caches I’ve deleted. I could not find a suitable OSS note. We’re on Netweaver 7.5 SP11 (03/18) on the frontend server and use Netweaver 7.4 SP16 in the backend server. Could somebody please give me some hints how to solve that?

Thank you,
Gerd

Dear Nabheet,

Dear Gerd

I trust you have taken all the steps to activate the app. Can you please provide the id of the app which you are trying to activate and what frontend and backend components you have installed on the system.

Thanks

Hi Gerd,

I think your frontend and backend components do not match with each other. Can you check in Fiori apps library if your system has the correct frontend and backend components in the respective systems?

Regards,

Jay
