Available to promise and capable to promise

Introduction

LN provides extensive functionality to support order promising. The following concepts are central to order promising:

  • An item’s ATP is the quantity that is available for customers either immediately, or on a specific time in the future.
  • An item’s Capable to Promise (CTP) quantity, is the quantity that is available in addition to the ATP, based on the spare production capacity of your production facility.

Available-to-promise and capable-to-promise support is important functionality for a reliable order acceptance procedure. To prevent over-promising of products to customers, LN may need to check on available inventory of finished goods, available sub-assemblies and components, and available production capacity.

You can use ATP checks as follows:

  • Online
    The sales employee performs an ATP check for one sales order during the sales order entry procedure or the sales quotation entry procedure.
  • Offline
    The customer does not immediately receive a delivery date from the sales employee. Instead, you prioritize multiple orders and promise dates later.

To support both situations, you can use the ATP Handling (cprrp4800m000) session during sales order entry, and also offline as a separate session.

Parameters

The following parameters, which you can specify in the EP Parameters (cprpd0100m000) session, determine how LN performs ATP and CTP checks.

  • Online ATP Update in EP
    If this check box is selected, every time you save a sales order line, LN immediately updates the sales order reservations and CTP reservations in Enterprise Planning and recalculates the ATP quantities. As a result, the next sales order line is checked against updated ATP quantities. This prevents the sales clerk from promising the same product ATP quantities to different customers.
  • CTP Check for Sales (for EP and OPS)
    If this check box is selected, and you insert the ordered quantity on a sales order line, LN performs an automatic ATP check. If the sales order line quantity exceeds the cumulative ATP quantity, a screen appears that includes an ATP Handling (cprrp4800m000) option. If you save a sales order line, and the ordered quantity exceeds the cumulative ATP, LN blocks the sales order line. You cannot save the sales order line if the ordered quantity is too high
