when you want to choose account under applicative user (to add entitlement) and you have more than 50 accounts, you can see only the first 50 accounts even in the next pages.
This is a bug and I can't find any solution in the patches.
(7.1.1 patch 5)
This sounds like a defect (product limitation).
I searched and it appears you are the first customer to report this as a limitation.
I recommend you open an RSA Customer Support Case for an issue if you want it addressed as a defect.
