In earlier releases due to store nodes being in the thousands and frequent demands, the real time availability monitor (RTAM) was unable to keep up with the additional demands coming into the system. In Release 9.3, the real time availability monitor is enhanced to address the additional requirements by the ship from store scenarios by determining when an activity (YFS_INVENTORY_ACTIVITY) has to be processed. Based on the calculated velocity of the item, the date and time of when the threshold changes is determined. Thus, when the RTAM runs, it process all the activities with the estimated time of threshold change that is less than the current time.
