Hello,
we got our SAP Application Enablement Tenant and IoT CF Tenant 1 week ago.
Trying to create a Freestyle IoT App with a created Thing following the information from https://www.sap.com/developer/tutorials/iotae-comp-buildappmc0.html we have the problem in step 6 Query Designer that we do not get entries in "Expand Associations" just "No Data".
Is this a bug or do we have different instruction for Query Designer? What can we do?

Hello,
was there a change in the IOT App Enablement System as the iot apps do not find the Things data anymore?
Also generating new IOT Freestyle Apps we do not get any Thing Types listed in "Select Properties Set" anymore...

Found the problem issue in changed required destination configiuration for Version 1.53 in Neo Cloud:
Important update for IoT Application Enablement customers using SAP Web IDE:
Due to a change in the authentication method, existing IoT Application Enablement customers using the SAP Web IDE need to reconfigure already configured destinations that require the Audience values.
The new Audience value will be of <tenantName.landscape> format. If your tenant name is iotae-onboarding and landscape is aws-live-eu10, the new Audience value will be iotae-onboarding.aws-live-eu10.
The Token Service URL value remains unchanged.
The destinations impacted include:
Example:
If the existing value in the Audience field is https//iotae-cireuseui1.authentication.sap.hana.ondemand.com/oauth/token/alias/iotae-onboarding.aws-live-eu10, it can be truncated to iotae-onboarding.aws-live-eu10.

I assume this might have to do with the changes required by each customer in the destinations used to connect from web ide to cloud foundry. Please check our customer and partner jam at https://jam4.sapjam.com/groups/kcKhhbRCPL3PQft2XM1d6X/overview_page/QMCk9FNB1Ck9ymiqJjdtiN for the detailed steps illustrated by Nicole. Every licensed partner or customer should have access to this jam.
The same information is also in the what's new section of our documentation relative to the 1.49 release here: https://help.sap.com/viewer/2b12f896e29d4c4e94323df5a26fcc25/1.52.0.0/en-US under the title "Important update for IoT Application Enablement customers using SAP Web IDE".

Hello Marcus,
our system was set up on 5th of march and IOT app enablement and Layout Editor in Web IDE have worked (after a fix on 27th of march) till friday. Looking at your information and checking the current Destination connections I get results i.e.:
Connection to "IOTAS-ADVANCEDLIST-THING-ODATA" established. Response returned: "404: Not Found".
Are there errors with the connections from our tenant and the destionations have to be configured again?

Hi Eberhard,
this issue is fixed now. The OData expand associations works again in the Query Designer.
Best Regards
Christian

Hello,
unfortunatelly it still do not work. To make more clear it is from the guide https://www.sap.com/developer/tutorials/iotae-comp-buildappmc0.html in step 4 the part "On Data Source step select:" where we now get no entries...
Thanks for the support so far.

There are multiple Videos on Youtube which show every little step in detail at https://www.youtube.com/playlist?list=PLWV533hWWvDnP5S4PLiC1d-J7hj1sjZn6 (this is also mentioned at developer.sap.com under iot application enablement). In my opinion the correct use of the layout editor has to be learned to make sure, you get it right when doing rapid prototyping. Priori knowledge in UI5 xml structure helps.
