Use Existing XSUAA Service Instance

[kiran_padarthi]

I am working on a CF based UI5 application, where we have two applications Admin and User application and a single Backend Java Application.

How Can I use Admin app XSUAA service instance into User App MTA.yaml (Existing XSUAA Service Instance) file?

mta.yaml:

you can just use the same service in all 3 applications (java + 2 UI apps)

Two ways.

1. Club the User + Admin into a single MTA

2. Use the same resource in both MTA (same xsuaa instance, the name would be same for xsuaa service in both mta)
