Hello colleagues,
when doing some tests with the HCP IOT service we finally wanted to display data of an IOT table in a SAP Fiori OVP page.
In general we can retrieve metadata and data using appropriate URIs.
In addition we could create a worklist app from a template within HCP WEB IDE and can display the IOT data.
Our target is however to have an OVP app and to create some cards to display the data for monitoring.
When trying to generate an OVP via WEB IDE => new project from template => SAP Fiori Smart Template Application => Overview Page Application
we are able to select the destination of our IOT service (Service: com.sap.iotservices.mms) and we can see the tables provided by this service.
After having supplied an annotation file we end up with problems in the step Template Customization: The field Datasource Alias is prefilled with
"com.sap.iotservices.mms". On filling the field Project Namespace an error is displayed:
Invalid format for "Datasource Alias" parameter value: The Datasource Alias must only contains letters and underscores.
It is possible to change the Datasource Alias definition into a value that is accepted, e.g. "iotservices" and to have the wizard finished.
When we try to create a new card on this OVP project we can choose the Datasource Alias (that has been modified when creating the OVP page) but then it is not possible to proceed in the Template Customization step since an "Entity Set" cannot be selected.
So we completely got stuck and lost Image may be NSFW.
Clik here to view.
Some important files are attached in a zip file for further investigations.
Would be great if we can have some help for our problem.
So many thanks in advance!
Mathias
