This process flow describes the master data that is necessary for Production Planning and Detailed Scheduling and in which sequence you have to maintain it. If you do not use APO as an ATP server, you can transfer most master data from a connected OLTP System and simply maintain part of the settings. For more information on which master data has to be maintained after transfer from the OLTP System, see OLTP - PP/DS Scenario and Integration Scenario: Master Data.

If you do not use APO as an ATP server but as a planning system, you have to perform an initial transfer of master data to APO using an integration model in the core interface. You must transfer the master data of all products that are to be planned in APO.

1. You create a supply chain model in the model/planning version master data or in the Supply Chain Engineer.
2. You create a planning version based on the supply chain model and you set the PP/DS: Change planning active indicator for the planning version.
3. You maintain a location (type: plant) in which a product is to be produced. You assign the location to the model by choosing Assign model on the initial location master data screen or you assign it in the Supply Chain Engineer.
4. You maintain the following data in the Product Master records in this location for the product and its components that are produced in-house:

• The lot size, scrap and rounding data in the Lot Size tab.
• Whether the product is to be planned automatically or manually (with or without check) by setting the appropriate indicator in the PP/DS screen, in the section entitled Automatic planning for all changes.
• Whether a product is to be produced in-house or procured externally in the GI/GR screen, in the Procurement field.

5. You maintain single-activity resources or multi-activity on which the products are to be produced. You define the working times and capacity for these resources. If you also use Supply network Planning to plan products, you maintain mixed-single or mixed-multi resources. These types of resources can used both in Supply Network Planning and Production Planning and Detailed Scheduling as it has both a bucket capacity and detailed capacity.

6. You maintain production process models for the product and the components that are produced in-house.

7. You maintain the transportation lanes between locations in the Supply Chain Engineer to model the transfer and delivery of products.
