Srinivasa,
As Karan said, you can have Fiori tiles, which will open various ITS transactions.
If you want to show ITS within Fiori (Fiori frame), then you need to build a reusable UI5 app which can render ITS transactions within an iframe. Since ITS transactions are already mobile enabled, I do not see any issue with this. Did you already tried any of these?
