Configuring ATP Check in the Sales and Supplying System (SAP Library

Configuring ATP Check in the Sales and Supplying System

Use

This section describes the settings required for transferring requirements and the ATP check in the sales and supplying systems.

Procedure

Check the checking group. In Customizing for Sales and Distribution choose Basic Functions ® Availability Check and Transfer of Requirements ® Availability Check ® Availability Check with ATP Logic or Against Planning ® Define Checking Groups.

Example: ATP group

Checking group	TotalSales	TotalDlvReqs	Block QtRq
02 (individual requirement)	A (single records)	A (single records)	X

Note

The value A must be set for the TotalSales and TotalDlvReqs fields.

The Block QtRq indicator must be set in both systems. Otherwise, the unlocking routines are not called in SAP APO, and the temporary quantity assignments remain in the SAP APO system.

Specify the default value for the checking group. In Customizing for Sales and Distribution choose Basic Functions ® Availability Check and Transfer of Requirements ® Availability Check ® Availability Check with ATP Logic or Against Planning ® Define Checking Groups Default Value. Make sure that there is a checking group set for individual requirements in the material master (see also: Maintaining the Material Master).

Example: Default value for checking group

System	Material type	Plant	*Checking group (AvailCheck* field)**
Sales system	HAWA	0011	02
Supplying system	HAWA	2200	02

Check the assignment of schedule line categories to the item category, which the system proposes automatically when it creates the item. In Customizing for Sales and Distribution under Sales ® Sales Documents ® Schedule Lines ® Assign Schedule Line Categories.

Example: Assigning schedule line categories

Item category	MRP type	Proposed schedule line category
TAN (standard item)	PD (MRP)	CP (MRP)

Check the assigned schedule line category. In Customizing for Sales and Distribution under Sales ® Sales Documents ® Schedule Lines ® Define Schedule Line Categories.

Example: Schedule line category (standard)

Sched. line cat.	Movement type	Req./Assembly	Availability
CP (MRP)	601 (GD goods issue: delvy)	X	X

Note

In the sales system, check the schedule line categories for account assignments. The schedule line category CS (leg/third-party business) should have the account assignment category X (all aux.acct.assgts).

Define a requirements class of your own if required. In Customizing for Sales and Distribution choose Basic Functions ® Availability Check and Transfer of Requirements ® Transfer of Requirements ® Define Requirements Classes.

Example:

Define your own requirements class (such as, ZBK) by copying the standard requirements class 041 (Order/delivery reqmt). You must set the Availability and Transfer of Requirements indicators.

Note

The check mode in SAP APO corresponds to the requirements class in SAP R/3.

Define your own requirements type if required, and assign this to the requirements class. In Customizing for Sales and Distribution choose Basic Functions ® Availability Check and Transfer of Requirements ® Transfer of Requirements ® Define Requirements Types.

Example:

Requirements type ZBK ® Requirements class ZBK

If required, specify determination of the requirements type using the transaction. In Customizing for Sales and Distribution choose Basic Functions ® Availability Check and Transfer of Requirements ® Transfer of Requirements ® Determination of Requirement Types Using Transaction.

Example: Determining the requirements type using transaction

Item category	MRP type	Requirements type	Origin of requirements type for requirements type determination
TAN	PD	ZBK	0 (strategy material master, then item cat, and MRP characteristic)

Check the control for the availability check. In Customizing for Sales and Distribution choose Basic Functions ® Availability Check and Transfer of Requirements ® Availability Check ® Availability Check with ATP Logic or Against Planning ® Carry Out Control for Availability Check.

Example: Control for availability check

Checking group 02/Checking rule A (SD order)

Checking group 02/Checking rule B (SD delivery)

The following indicators are set:

In/outward movements:

Incl.purchase orders
Include sales reqmts
Incl.ship.notificat.

Replenishment lead time

Check without RLT

Specify determination of the requirements transfer using the strategy group.

Define a strategy of your own if required. In Customizing for Production choose Material Requirements Planning ® Master Data ® Independent Requirements Parameters ® Planning Strategy ® Define Strategy.

Example: Strategy

Define your own strategy (such as A1) by copying the standard strategy 10.

Set the requirements type for customer requirements straight to ZBK (order/delivery reqmt).

Define a strategy group of your own if required. In Customizing for Production choose Material Requirements Planning ® Master Data ® Independent Requirements Parameters ® Planning Strategy ® Define Strategy Group.

Example: Strategy group

Strategy group: A1

Main strategy: A1

Enter the strategy group in the material master on the MRP 3 tab page.

Note

The strategy group refers to a strategy. The strategy refers to the requirements type. The requirements type refers to a requirements class.

The requirements class from SAP R/3 is transferred to the SAP APO system during the ATP check of the sales order, and results in the check instructions as the check mode together with the business event. The prerequisite for this is that the relevant check modes have been created in SAP APO, for example, by transferring the ATP Customizing settings using the SAP APO Core Interface from SAP R/3 to SAP APO (see Integration Model: ATP Customizing indicator is set).

All other applications do not transfer a check mode. In this case, the check mode is read from the SAP APO product master. For this reason, you must enter the check mode in the SAP APO product master.
