Clear Cache in Server Level to avoid clearing the Cache in Local machine

STEP 2: Clear the CA PPM Server cache.
a. Login to CA PPM application as an admin user 
b. Modify the URL field to: http:///niku/nu#action:security.caches
c. Click Caches tab, click FLUSH ALL button
d. Click Groups tab, click FLUSH ALL button 
e. Logout
f. Login and check if problem persists.


That's Correct, Its better to be doing via CSA/Server and if you use flush all from security.caches and user don't log out then he/she will be in the same server and it will be quicker
