This field applies to APS.
Enter the number of temporary copies of the planner database that can exist in the server's memory at the same time for APS planning functions. When you use the Get ATP or Get CTP functions, the system creates a temporary copy of the planner database in memory, on which it runs the calculations to determine the projected date for the order or line item. If multiple workstations run the Get ATP/CTP function simultaneously, the available memory on the server may be exceeded. Use this field to limit the number of concurrent database copies to within your server's memory capacity.
The Availability Results dialog, which displays during a Get ATP/CTP process for a line item, includes a Quantities button, which displays the quantity of the line item that can be completed by the request date. Clicking the Quantities button creates two additional copies of the planner database in memory. These copies remain in memory until the Get ATP/CTP dialog is closed. Therefore, if all your users are likely to use the Quantities button, multiply your base Max What-If Databases figure by three.
EXAMPLE: Suppose you have ten SyteLine client machines that will potentially use the Get ATP/CTP feature, and five of those machines will likely use the Quantities button on the Get ATP/CTP dialog. Your worst-case requirement for what-if databases would be 10, plus an additional 10 for the five clients using the Quantities button, for a total of 20. If you do not anticipate all 10 clients using the Get ATP/CTP feature simultaneously, adjust the figure appropriately.
