The Xpress Teller Funds In screen was specifically designed to allow for a single place to bring in cash, checks, in-house drafts, and now misc. advances (cash advances on a Visa, for example), all on a single screen. It was specifically not our intent to replicate the ability to enter 588 outside checks and 126 in-house checks and 60 misc. advances, because to do that would mean having to split into 3 separate screens, same as in the existing teller system.
So if you have a member who brings in more than 20 outside checks, the teller will either need to combine the items into a single entry in Xpress Teller (you can still adjust the count for use with your deposit item fee, if applicable), or use Standard Teller instead for that transaction.
