I'm trying to add multitenancy to my SAPUI5 Fiori applications which used Managed Application Router in SAP Cloud Foundry.
Is there a way to subscribe to a sapui5 application that uses Managed Application Router in provider sub-account from a tenant sub-account?
It is not possible at the moment as far as I know.
To be able to have true Multitenancy, each tenants identity validation must be seperated. And this is only possible with standalone approuter which has an environment variable called 'TENANT_HOST_PATTERN' which is a regex pattern. Approuter uses this regex pattern to isolate each tenants login flow.
BTW : If you have any conceptual questions about multitenancy in SAP BTP Cloud Foundry I would strongly reccomend to read this
Best,
