Settings for the CTP Process - SAP Documentation

Prerequisites

You have maintained the ATP Customizing in SAP R/3. See also: ATP Customizing in R/3
You have transferred the master data and the ATP Customizing to SAP APO. See also: Transferring Master Data .

Settings in the ATP Customizing in SAP APO

Define checking mode

During the Customizing transfer the system created a check mode in SAP APO for the SAP R/3 demand class of the planning strategy . In the Production Type field of the Check Mode you choose the setting Characteristic Evaluation.

Define check instructions

You add the check instruction for the business events A and AE:

Field	Input Value
Product Check	First Step
Start Production	Availability Check First, then Production
Time of Production	After Executing all Check Methods
Re-create receipt elements	Set indicator

Define Check Control

You add the settings of the check control for the ATP group that you have transferred from SAP R/3 and the business events A and AE:

Field	Input Value
Past Receipts	Consider Past Receipts

Settings in the PP/DS Customizing

Define Planning Procedure for the Finished Product

You create a new PP planning procedure for the finished product by copying the PP planning procedure 3 Cover Dependent Requirements Immediately. You use the planning procedure to control not only the process of planning, but also the creation of fixed pegging relationships. In the planning procedure that you have created, you make the following settings:

In the field ABAP Class for the CTP Scenario, you enter the ABAP class /SAPAPO/CL_RRP_CTP or /SAPAPO/CL_RRP_FIX . For information about the differences in system behavior depending on the class that you use, see the document Comparison of the ABAP Classes /SAPAPO/CL_RRP_CTP and /SAPAPO/CL_RRP
In the field Fixed Pegging in CTP, you choose the option Create Fixed Pegging Relationships .

Multilevel Planning in the CTP Process

If you want to carry out multilevel planning in the CTP process , for example, to check important assemblies and components , create a new planning procedure for these assemblies/components with the event Create or Change a Dependent/Stock Transfer Requirement in PP/DS, in conjunction with one of the following actions:

Cover dependent/stock transfer requirements immediately
Cover dependent/stock transfer requirements immediately if possible
Cover dependent/stock transfer requirements immediately with existing receipts

In the planning procedure that you have created, choose the option Create Fixed Pegging Relationships in the field Fixed Pegging in Multilevel Planning.

Alternatively, you can use the BAdI /SAPAPO/RRP_IO_CHECK Extend Multilevel Planning (CTP) to create multilevel fixed pegging relationships in the CTP process. If you do so, you do not need to make any settings in the planning procedure. If you use the BAdI the system automatically creates a fixed pegging relationship, as soon as the system has assigned the requirement element to a receipt element.

Settings in the Product Master

In the product master of the finished product, check that the check mode for which you defined the production type Characteristic Evaluation has been transferred from SAP R/3.
Enter the PP planning procedure in the product master of the finished product.
For important components that must also undergo a CTP check, enter the PP planning procedure that you have created for these components in the product master of the component.
