This typically happens when the deposit is being entered after the DSS has already polled into R365. Please check with your Store Managers to make sure all deposits are entered during the day, before overnight polling. If the deposit has been entered after polling, you can enter them manually in the DSS or simply re-poll the DSS.
If you are entering the deposits before polling, and they are still not coming over, please contact R365 Support and include a POS report of the deposit entered, including a time stamp showing that they were indeed entered the day before polling.
