Figure 75: Planned Orders and Production Orders
SNP planned orders are used to plan the in-house production of a material. Planned orders already contain the basic dates within which production should take place.
They also contain dependent requirements, which are the component requirements needed for production. Capacity can be planned based on planned orders.
For final production execution, the planned order is converted into a manufacturing order, that is, a production order (PP) or a process order (PP-PI). The conversion of and SNP planned order into a production order is not possible in SAP SCM, and can only be carried out in SAP ECC.
When a demand falls within the production horizon, it is no longer planned in the SNP planning run but planned in the production planning run in PP/DS.
In Production Planning and Detailed Scheduling, PP/DS planned orders can be created or changed manually across the entire time axis, regardless of the production horizon. During automatic planning in PP/DS (production planning run), only orders within the production horizon are created. In Supply Network Planning, orders cannot be created or changed within the production horizon.
Orders within the production horizon that can be planned by Production Planning and Detailed Scheduling are still displayed in Supply Network Planning as aggregated receipts in the defined bucket. The conversion of a PP/DS planned order into a production order in SAP SCM, is possible and sensible.

Figure 76: Production Planning Run Overview: PPM Explosion
From the point of view of a bill of material (BOM), the production planning run performs the following activities:
• The production planning run first determines the independent requirements for the finished product, which can include sales orders and planned independent requirements. If sufficient stock or receipt quantity is not available, the production planning run generates a planned order.
• The PPM/PDS of the planned order for the finished product is exploded and dependent requirements are generated for the assemblies. Dependent requirements are requirements that are derived from the BOM structure.
• At the next BOM level, the dependent requirement represents demand for each assembly. If sufficient stock or receipt quantity is not available to meet this requirement, the production planning run generates a planned order.
• The BOM of the planned order for each assembly is exploded and dependent requirements are generated for the raw materials.
• At the lowest BOM level, the production planning run determines the requirements again. If sufficient stock or receipt quantity is not available, the production planning run generates a purchase requisition for external procurement of raw materials.
• If planning is single level, only the receipts and dependent requirements are produced for the selected product. Given multi-level planning, the complete BOM structure is exploded.

Figure 77: Integration of SNP and PP/DS Orders
The PP/DS horizon and SNP production horizon are defined in calendar days, starting from today's date. The PP/DS horizon can be defined globally in the definition of the planning version. You can define both horizons for each product in the location-specific product master on the PP/DS tab page. The settings in the product master override the global settings. The two horizons may overlap to define an area where SNP can be used alongside PP/DS for planning.
SNP planned orders can only be created or changed in SNP, while PP/DS planned orders can only be created or changed in PP/DS. The SNP planning run only creates SNP planned orders with an end date outside the SNP horizon. Automatic PP/DS planning only includes requirements that are within the PP/DS horizon.
The production planning run deletes all non-fixed SNP planned orders that have an end date within the PP/DS horizon and creates PP/DS planned orders for requirements that are within the PP/DS horizon, such as planned independent requirements, sales orders, or releases for stock transfers.
The product master also includes the Firm production and Fix transports settings.
If these indicators are not set, PP/DS deletes SNP planned orders within the production horizon and external procurement within the stock transfer horizon.
If SNP planned orders include requirements outside the PP/DS horizon for example, these requirements are deleted during the PP/DS planning run and no PP/DS planned orders are created. To prevent this, you have to convert the SNP planned orders into fixed PP/DS orders before the PP/DS planning run. You can trigger this conversion interactively from the product view or schedule a periodic background conversion in PP/DS. During this conversion, you can set whether or not you want unfirmed or firmed orders to be created with or without a conversion

indicator. You can also choose the lot sizing procedure that you want to use to create the orders and whether or not you want the SNP sources of supply to be adopted. The end date of the SNP planned order is used for scheduling. To select the conversion function, go to Production Planning → Environment → Conversion of Supply Network Planning → Production Planning in Background.
Figure 78: Converting Planned Orders in SAP SCM
Planned orders are used to plan the in-house production of a material. SNP planned orders contain only the basic dates within which production is to take place, and no specific operation dates. Alternatively, PP/DS planned orders already contain all production dates and times.
Both SNP and PP/DS planned orders can be transferred to the SAP-ECC system.
The relevant ECC planned orders contain only the basic dates, in which production is to take place, and no specific operation dates. These planned orders also contain the dependent requirements for both SAP-SCM and non-SAP-SCM components.
The procurement of these components can be planned in ECC based on these dependent requirements.
If production planning takes place in SAP SCM-PP/DS, the planned orders have to be converted from SAP SCM into production orders. The only difference between an SAP-SCMproduction order and an SAP SCM planned order is the conversion indicator. If you set the conversion indicator in SAP SCM, a corresponding ECC production order is created in ECC. This order assumes the production dates that have been determined in SAP SCM. Similar to every ECC manufacturing order, it also contains all the functions, such as printing order documents and displaying confirmation messages, which are needed to execute production.
SNP planned orders cannot be converted fromSAP SCM to ECC production orders.
