You can run an ATP check for planned orders that you have planned using the Rapid Planning Matrix. It enables you to determine whether the required components, calculated by the matrix for the individual planned orders, are available for the scheduled requirements date.
Note
You can use the ATP check for all products, not only RPM products, for which you have set
Single Explosion of iPPE
.
The ATP check for planned orders for RPM products is a subfunction of the ATP check for orders in Production Planning and Detailed Scheduling (PP/DS). For more information on the ATP check in PP/DS, see ATP Check in Order .
Only the product availability check and the check against forecast can be used for planned orders. Other functions of the global availability check, such as the rule-based availability check, are not available.
In Customizing for
Production Planning and Detailed Scheduling (PP/DS)
under
Maintain Global Parameters and Defaults
, you have entered the business event
PP
in the
Result of Planned Order Check
field on the
Execution
tab. The business event PP is provided as standard for checking planned orders.
In Customizing for the
Global Availailable-to-Promise (Global ATP Check),
you have created a
check mode
for checking the availability of components. You do so in the IMG activity
Maintain Check Mode
.
You can select any entry for the check mode in the
Assignment
field. In the
Production Type
field, select
Standard.
In the IMG activity
Maintain Check Instructions
, you have defined instructions for checking planned orders. You do so by creating an entry for your
check mode
and assigning the
business event PP
. You have made the following settings in the remaining fields:
Product check
field: First step
Prod.
Allocation
field: No check
Forecast
field: No check (or ‘Second step’ if you wish to use the check against forecast).
Remain.
Reqmnt
field: Do not create remaining requirement
Start product.
field: Availability check only, no production
You can select any entries for the remaining fields, because production is not being triggered and the ATP check is not multi-level.
You have specified which components are to be checked in the ATP check in the APO. You do so by entering an
ATP group
and a
check horizon
for the
check mode
you defined in Customizing in the location product master for these components.
If you wish to run the ATP check automatically when you transfer the order sequences to an external production control system, you must specify how the ATP check is to take place and how the system should react if not all the components being checked are available. You make these settings in Customizing for
Model Mix Planning
in the IMG activity
Define Transfer of Order Sequence to Production
in the
ATP mode
field. Refer to:
Transferring Order Sequences to Production
.
You can run an ATP check automatically for the planned orders when transfer the order sequences to a production system. This guarantees that planned orders are transferred to production only if their components are actually available.
You can start the ATP check interactively from planned order management on the ATP Check tab page. The results from the check are displayed immediately on this tab page. This enables you to see at a glance whether certain components are still missing.
During the ATP check, the system checks each planned order, which you have selected in planned order management, for example. It checks whether the components are available, which the Rapid Planning Matrix has calculated for each order and which are relevant for the ATP check. The
ATP group
that you have entered in the location product master for the components determines the scope of the check, such as the check against warehouse stock, or the check against planned receipts.
The available quantities of a component are displayed as the confirmed quantity on the
ATP Check
tab page in planned order management. The
missing parts indicator
indicates which components are missing. The planned order for the RPM product is not confirmed until all the ATP-relevant components are available.
The SAP APO fixes the confirmed components in the planned order for the RPM product, to protect them from changes caused by the next planning run.
