Variant Management not Working in BTP Launchpad service

[UdayMS]

Hello Folks

I have deployed SAP MTA application with Fiori module on SAP BTP Launchpad service. Our custom UI5 application consumes odata from on premise S/4 HANA. We have used Standard Fiori elements list report for some applications and Smart Controls for others. Strangely the Variant management for Selection screen has stopped working and when I try to Save it getting the error "Unable to Load Data. This can happen if you are not connected to the internet or if any underlying system component is not available". Attached in screenshot also.

Its happening irrespective of having any custom fields in selection screen

Strangely, it works perfectly fine when I run from Local BAS using index.html and flp.html. But when Run through BTP launchpad getting this error.

Our UI5 version of BTP Launchpad service is 1.103.0.

Attached in F12 trace where iit says bad request

Pls help me with this issue how to resolve. If any issue with my code or any settings

Thanks

UDay

Hi Uday,

sapui5 version 1.103 have a bug that breaks the creation and deletion of variants. SAP working on fixing it in the next release 1.104.
A workaround solution until then is available for custom applications by specifically setting older version of sapui5 (such as 1.96.x) from the manifest of applications.See documentation

Hi Milan

Thanks for the suggestion. I will try to set the ui5 version of my app to a lower level and try.

Thanks
