[masa_139]

After you create a custom app or extend a standard Fiori app, tile is required for launching the app.

Here are screenshots explain the launchpad objects relationship.

1. User -> Role (Transaction: SU01)
2. Role -> Catalog/Group (Transaction: PFCG)
3. Catalog/Group -> Tile (launchpad designer)
4. Tile -> Intent ( launchpad designer, Tile)
5. Semantic Object (Transaction: /UI2/SEMOBJ and /UI2/SEMOBJ_SAP)
   
6. Intent -> Application Alias (launchpad designer, Target Mapping)
7. Application Alias -> App URL (in LPD_CUST)
   Application Alias -> Component ID (in LPD_CUST)
8. App -> Component ID in Configuration.js (Transaction: SE80)

Example app is Approve Purchase Order.
