Maintain Check Mode:

Check Mode

The check mode derived from the product master record and the business event, determine the type and scope of the checks to be carried out. In addition, the check mode controls consumption using the forecast.

The SD (R/3) uses the requirements class of the requirement as a check mode. The requirements class (via the strategy group in the material master) is transferred to the location-specific APO product master (tab page ATP). No plausibility check takes place. You should therefore not enter any other check mode in the product master, as the check mode in the product master must match the requirements class from the SAP R/3 system.

Assignment Mode

Determines how sales orders consume the forecast. Only one type of consumption is possible for each requirements strategy.

Production Type

The production type controls how the system is to execute the product availability check:

• Based on ATP time series (standard)

• Based on Production Planning and Detailed Scheduling (characteristics evaluation)

• As a multilevel ATP check

• As a kit check

Use

• Standard

With this setting, the system executes the availability check based on ATP time series. Production Planning and Detailed Scheduling (PP/DS) is only called if receipt elements ( planned orders or purchase requisitions) have to be generated during the check. If characteristic value assignments were transferred to the availability check, these are taken into account. A check at finished product level, which perhaps should have been executed earlier, is carried out through characteristics-based ATP. Characteristics-based ATP is a function of the basic method product availability check and is activated automatically if characteristic value assignments are transferred to the availability check and the respective product is maintained for characteristics-based ATP. You maintain the settings for characteristics-based ATP in Customizing for Advanced Planning and Optimization under Global ATP -> Product Availability Check -> Maintain Characteristics View. For more information, see the documentation for Maintain Characteristics View.

• Characteristic Evaluation

With this setting, the system executes the availability check at finished product level based on PP/DS. Both the check at finished product level and the creation of receipt elements are carried out using PP/DS. In PP/DS, the availability check is performed using a net requirements calculation. The ATP check based on PP/DS is not aggregated, unlike the standard ATP check. For this reason, the call takes place in backorder processing in individual records. This form of ATP check can therefore not be used in connection with backorder processing in the case of high order volumes. The following functions are not supported:

o Scope of check

o Availability check considering the checking horizon

o Shortage check (online vs. batch)

o Specific availability check for sublocation and version

o Further restrictions are listed in SAP Note 601813.

You can also use the ATP check based on PP/DS in connection with fixed pegging. The system can therefore take account of fixed pegging in the ATP check separately. A prerequisite of this is that, in the planning procedure, in the ABAP Class for CTP field, you select a suitable ABAP class for the following processes:

o CTP process

You use planning procedure 3 (cover dependent requirements immediately) and enter class /SAPAPO/CL_RRP_FIX.

o Order acknowledgement with order receipt

You use planning procedure 4 (planning in the planning run) and enter class /SAPAPO/CL_RRP_FIX.

o MRP process

You use planning procedure 4 (planning in the planning run) and enter class /SAPAPO/CL_RRP_FIX_ONLY.

Note that the system takes the following into account if you have made the Characteristic evaluation setting when using ATP/ CTP with fixed pegging:

o The scope of check is always taken into consideration if you use fixed pegging.

o The checking horizon is always considered when you use CTP or fixed pegging.

• Multilevel ATP Check

During a multilevel ATP check, an ATP tree structure is built in the main memory that represents a multilevel BOM and substitutions that resulted from a rule evaluation. The receipt elements are created during a later conversion of the ATP tree structure in PP/DS. If a rules-based ATP check is carried out at component level, a stock transport requisition is created for a location determination during the conversion that takes place later in PP/DS. The stock transfer indicator that you can set in integrated rule maintenance (see location determination activity) does not have any influence on this system response. The characteristics-based product availability check at component level is not supported in this process.

• Kit check (KIT)

During a kit check, the kit is first checked before the components of the kit are determined and checked individually. The components are correlated at kit level with

regard to time and quantity. Note that the system only checks the components if you have activated production in the check instructions. When a kit is ordered, it is always delivered completely. However, since all components of the kit are independent products, these can also be checked and delivered independently of one another when a kit component is ordered. The kit is modeled in the iPPE master data in the form of an assembly group. In contrast to the multilevel ATP check, the component requirements from SAP APO are returned to the calling OLTP system (SAP CRM for example) in the kit check. The kit check is only supported for sales orders from SAP CRM.

Note

If you have selected a check mode for a finished product that permits the multilevel ATP check, Capable-to-Promise (CTP) may on no account be configured in the check mode or in a rule (see location determination activity) for a component. Mixtures of multilevel ATP check and CTP are not supported.

Rounding Procedure

Name of the condition record that the system uses to determine a packaging specification.

Use

The rounding procedure contains all of the information from the packaging specification that is necessary for rounding. The system uses this information to round the requirements quantity or the confirmed quantity from the availability check.

For more information about packaging specifications, see SCM Basis -> Packing -> Packaging Specification -> Determination of Packaging Specifications -> Define Determination Procedure in the Implementation Guide (IMG) of SAP APO.

Dependencies

The following conditions must be met for the system to round:

• You have set the indicator Rounding Procedure Active.

• You have set the indicator that permits an availability check with rounding in the OLTP system.
