1.       Some time, after we added one OAF page, but when we checked and use it, it will show you don’t have right to execute this responsibility.

We can go to functional Administrator / Home / Core Services/ Caching Framework / Global Configuration / Clear All Statistics.

Otherwise we will wait for refresh after 15 minutes

2.       How can I find the data source for OAF page.

First we can enable the ‘Diagnostic’s on the OAF page By setting FND: Diagnostics

. And ‘about this page’ by setting Personalize Self-Service Defn

Login out and login in again, if you still cannot find the about this page and Diagnostic, we need to use the step 1 to clear the cache.

3.       How to disable below message
