Conversion of SNP and CTM Orders into PP/DS Orders (SAP Library

Conversion of SNP and CTM Orders into PP/DS Orders

Use

In Production Planning and Detailed Scheduling (PP/DS), if you want to execute detailed planning for the receipts you have created with Supply Network Planning (SNP) or with Capable-to-Match (CTM), you have to convert the SNP or CTM orders into PP/DS orders. During the conversion, the system creates PP/DS orders from the SNP or CTM orders and then deletes the SNP/CTM orders. You can convert orders as follows:

· You can execute a mass conversion for all SNP or CTM orders that begin in the PP/DS horizon or in a larger conversion horizon.

· In interactive planning, you can specifically convert individual SNP or CTM orders within or outside the PP/DS horizon.

You execute the conversion within a planning version. The system takes account of the current propagation range when creating the PP/DS orders.

Prerequisites

You have defined resources and sources of supply for SNP and PP/DS that are consistent with each other. For more information, see Integrating SNP and PP/DS.

You cannot convert the following orders into PP/DS orders:

· TP/VS orders

· Product substitution orders in SNP

Features

You use a special heuristic based on the algorithm /SAPAPO/RRP_SNP2PPDS for the conversion, such as the standard heuristic SAP_SNP_SNGL. The mass conversion that you can call in the area menu for Production Planning is an exception. If you have upgraded to SAP APO 4.0, the system performs the mass conversion using the report /SAPAPO/RRP_SNP2PPDS. This report was available in SAP APO 3.1.

Procurement Quantity Calculation

To determine the procurement quantities of the PP/DS orders from the receipt quantity of an SNP or CTM order, PP/DS performs a procurement quantity calculation during the conversion (“lot formation”). You have various options in this situation. You could perform a 1:1 conversion or an SNP-independent redetermination of the procurement quantities using the lot size settings from the location product master. For more information, see Procurement Quantity Calculation for SNP-PP/DS Conversion.

Source Determination

The procedure selected determines which sources of supply PP/DS uses to create the PP/DS orders. You have the following options:

· PP/DS determines the sources of supply independently of SNP using automatic source determination from PP/DS.

· PP/DS determines the source of supply from the SNP/CTM order being converted.

For more information, see Source Determination for SNP-PP/DS Conversion.

Order Status

In the settings, you can specify the status with which you want the system to create the PP/DS orders. You have the following options:

· The PP/DS orders have the status firmed output

You can only make manual changes to the receipt quantities of PP/DS orders with the status firmed output.

· The system sets the conversion indicator for the PP/DS orders.

After the transfer to a connected SAP R/3 system, the system immediately and automatically converts planned orders and purchase requisitions (whose conversion indicators are set) into manufacturing orders or purchase orders.

If you execute the conversion in the active planning version 000, the system performs the conversion checks defined in the conversion rule (such as an ATP check) before the conversion indicator is set. The system only sets the conversion indicator if the PP/DS order passes the checks without any errors. For more information, see Converting Orders.

Scheduling the PP/DS Orders

If you have set forward scheduling, the system begins at the start date/time of the first activity in the SNP/CTM order as standard. In backward scheduling, as standard, the system begins at the end date/time of the period that contains the availability date/time of the SNP/CTM order being converted.

You can specify a safety time for backward scheduling. In this case, the system does not start backward scheduling at the end of the period but at a correspondingly earlier date/time.
