Hi Naveen.
What is the UI library version for SAP_UI at SP12. You should be at 1.28.11
SAP Fiori - UI Add-on SP12 notes list, SAPUI5 library 1.28.11
Also ensure, you have admin access for assigning catalog to your users.
SAP_UI2_ADMIN_700
Few steps you can try. Delete the role and create the role again. I hope some cache issues might persists. Hope you clear all the system cache and browser caches.
Run below reports :
Run the report /UI2/CHIP_SYNCHRONIZE_CACHE. Make sure there is no error in the table /UI2/CHIP_CHDR
Run the report /UI2/DELETE_CACHE_AFTER_IMP.
/UI2/DELETE_CACHE
Run the report /UI5/UPDATE_CACHEBUSTER.
/UI2/INVALIDATE_GLOBAL_CACHES
