HI Viswa,
I want to make a copy (not extension/extension project) and then modify it.
Today I found (and fixed) that in one of the files "z" was missing in new app name.
After correction app runs without problems via sandbox. But after deployment it still returns the same error at fiori launchpad.
PS: I cleared cache:
1. In browsers (I checked 3 different browsers)
2. Gateway via: flp*cache*delete, flp*cache*delete*after*imp, /iwfnd/clear_cache
3. Backend via /iwbnd/clear_cache
I Think that now folder structure of app at server is somewhere wring (wasn't updated at last deployment), but don't know how to find and fix it...
