Online ATP updateIf the ATP is to be used to support order acceptance, it must be kept up-to-date. To update the ATP, choose one of the following methods:
To switch the online ATP update on or off for all plan items, use the Online ATP Update in EP check box in the Planning Parameters (cprpd0100m000) session. If the Online ATP Update in EP check box is selected, to switch the online ATP update on or off for a particular plan item, use the Online ATP Update check box in the Items - Planning (cprpd1100m000) session. Note If you use ATP functionality for an item that has no master plan, no online ATP updates are required; in this case, the ATP is always computed online. Online updating of ATP requires additional system performance, especially during sales order entry. Recommendations:
