I'm working with Mendix for a while now and all is well. The thing is, when I wanted to deploy it to the hanatrial environment again, I got confused.
The tutorials state that you need "SAP HANA Schemas & HDI Containers (Trial)" service and select the hanatrial-schema, but that is not there anymore. Only the non Trial version is available. Have a look at the screengrabs:
So when I select the securestore option setting up the BTP environment, all works, but it could confuse people.
Hint: Would be best to show the screengrab of the BTP which services need to be instantiated before you start deploying.
Hope this helps
ps: no Sap managed Tag "Mendix"?
