Under- and Overconfirmation Alerts

Use

For all customer requirementsthere is a requested quantity and a confirmed quantity. If the confirmed quantity is less than or more than the requested quantity, the system issues under-or overconfirmation alerts.

Prerequisites

So that under- and overconfirmation alerts are displayed in the Alert Monitor you must:

Define a PP/DS Alert Profile

(Choose Advanced Planning and Optimization Supply Chain Monitoring Alert Monitor Overall Profile.)

There is no fixed assignment between the requested quantity and the confirmed quantity of a customer requirement.

Therefore, for the generation of under and overconfirmation alerts, it is necessary to define periods ( buckets) in which the requested quantities and confirmed quantities can be aggregated and compared.

In the PP/DS Alert Profile, you can use the period type to define the periods (seconds, minutes, hours or days) on which under- and overconfirmation alerts are based.

You can also create your own period types for under- and overconfirmation alerts, without making any modifications.To do so, you must first define the period types in the tables /SAPAPO/DETSTATB and /SAPAPO/DETSTATT and then integrate them into the under- and overconfirmation alert determination process by using the Business Add-In /SAPAPO/AM_CNF_ALERT.

If you have not selected a period type, the alerts are determined on the basis of seconds.

For more information, see Monitoring PP/DS Alerts .
Select the alerts types Confirmed quantity less than requested quantity and Confirmed quantity exceeds requested quantity.

On the PP/DS tab page, under Order Alerts - Product-Dependent, choose the alerts you wish to use.
Assign this PP/DS Alert Profile to your Overall Alert Profile.

Features

Generating Underconfirmation Alerts

The system generates an underconfirmation alert for a customer requirement in a certain period under the following conditions:

The confirmed quantity is less than the requested quantity
The cumulative confirmed quantity is also less than the cumulative requested quantity

Generating Overconfirmation Alerts

The system generates an overconfirmation alert for a customer requirement in a certain period under the following conditions:

The confirmed quantity is more than the requested quantity
The cumulative confirmed quantity is also more than the cumulative requested quantity

Example

The following example illustrates the way in which under- and overconfirmation alerts are determined.

It has been assumed that the system determines the alerts on the basis of days.

	10.1.	11.1.	12.1.	13.1.	18.1.	20.1.	24.1.	25.1.	26.1.	27.1.	03.2.
Requested quantity	10	10	8	10	10	10	20	0	0	5	5
Cumulative requested quantity	10	20	28	38	48	58	78	78	78	83	88
Confirmed quantity	9	10	10	10	9	0	0	15	15	10	0
Cumulative confirmed quantity	9	19	29	39	48	48	48	63	78	88	88
Confirmed quantity – Requested quantity	-1	0	2	0	-1	-10	-20	15	15	5	-5
Cumulative confirmed quantity – Cumulative requested quantity	-1	-1	1	1	0	-10	-30	-15	0	5	0

Overconfirmation alert

= The system determines under/overconfirmation alerts

Activities

Clearing Underconfirmation Alerts

First, carry out procurement planning for the product to generate procurement proposals for in-house production, or external procurement to cover the customer requirements.

You can then determine whether the customer requirements can be met on time, for example, using the ATP check.

Clearing Overconfirmation Alerts

You can either resolve overconfirmation situations manually in interactive backorder processing or by using backorder processing in the background.

See Backorder Processing and Backorder Processing (Sales Scheduling Agreements)

Business-Add-In (BAdI)

You can use the Business Add-In (BAdI) /SAPAPO/AM_CNF_ALERT ( Under-/Overconfirmation Alerts ) to:

Edit the order types that are relevant for the determination of under- and overconfirmation alerts.
Implement customer-specific period types: The periods (buckets) in which the requested quantities and confirmed quantities are grouped and compared with one another.
To influence the time zone that is relevant for the determination of under- and overconfirmation alerts.
