Computing item ATPThe available-to-promise (ATP) is calculated for items with supply in order horizon or master horizon. The order horizon ATP is based on the demand and supply in the ATP field of the Item Order Plan (cprrp0520m000) session. In the Item Master Plan (cprmp2101m000) session, several fields give an indication of the item quantity that is still available at a certain point in time:
The projected inventory shows the inventory level as it is expected on the basis of the previous inventory, the expected demand, and the planned supply. For more information, refer to To compute the projected inventory The available to promise (ATP) is an indicator of inventory availability that is specifically geared to the process of order acceptance. In the Item Master Plan (cprmp2101m000) session, the ATP is shown in two formats:
