In SAP APO, Production Planning/Detailed Scheduling (PP/DS) is used to generate procurement proposals to meet the production requirements. This component is also used for defining resource plan and order details. You can also plan for critical products to reduce the lead time and to improve time delivery performance.
PP/DS can be used to create executable plans and to achieve the following −
- Improve the on-time delivery performance for critical products
- Reduce lead times
- Improve coordination between resources and better procurement process
- Reduce the stock cost
PP/DS is integrated with other SAP APO components. For example, with demand planning to create a demand plan and to move PIR to PP/DS to create procurement proposals.
Transaction and master data from the OLAP system is moved to APO and after order processing planning, results are moved to APO system.
Integration of PP/DS with SAP APO applications
Let us now discuss integration of PP/DS with SAP APO applications.
Integration with Demand Planning
Demand planning is used to meet the market demand for critical products after considering different factors and the result of demand planning is a demand plan. Demand plan is moved to PP/DS to raise procurement proposals for both external system and internal procurement process.
Using Demand Plan, demand planning is executed for customers and planned independent requirement results are transferred from DP to PP/DS to cover PIR by creating procurement proposals.
Following is the Process Flow −
- Step 1 − First step is to start with the release of demand plan to Supply Network Planning. Demand plan can be released as mass processing or online.
- Step 2 − Consider the release period same on PP/DS horizon and Supply Network Planning horizon.
- Step 3 − Copy requirements to target planning version, resulting in a demand plan to Supply Network Planning, which in turn triggers an event in PP/DS for products.
- Step 4 − Action takes place as per Planning Procedure for mentioned products.
- Step 5 − Execution of PP/DS Planning.
Integration with SNP
Supply Network Planning (SNP) ensures that product quantities are available at the right time, right place without overloading of resources in production and transportation process. SNP defines the quantities in which products should be procured, produced, or transported. PP/DS defines lot sizes of products to be procured, and sequences of planning order.
Both the methods are integrated and planning is performed for different task distribution.
Supply Network Planning and PP/DS Planning Tasks
SNP and PP/DS are defined for different phases - SNP planning is used for medium-term objectives and short-term planning is for PP/DS. The horizon for SNP planning and PP/DS planning are same and the planning area doesn't overlap.
When the same planning version is used for SNP and PP/DS, it is also possible to convert SNP orders into PP/DS orders.
PP/DS Alert Monitoring
You can monitor alerts raised in PP/DS planning using the Alert monitor. You need to define an alert profile relevant for to your planning. Different alert types are created in PP/DS.
Alerts Related to Relationship between Orders or Operations
- Dynamic pegging with date/time alerts
- Fixed pegging alerts
- Quantity alerts for pegging
- Shelf life
This option is checked in the product master. Navigate to SAP Easy Access − Advanced Planning and Optimization − Master Data − Product.
The system compares the shelf life planning with the actual shelf life of receipt during planning.
When shelf life requirements are met, pegging relationships are created.
- Relationship between Operations
Alerts Related to Procurement Planning
When procurement planning heuristic is run, different PP/DS alerts can be raised w.r.t Planning. Following are the common alert types −
Procurement Planning Exceptions
In PP/DS alerts related to procurement planning are generated when you define setting in customizing. Navigate to Application logs for PP/DS, and define and maintain exception groups.
To check exception message, you can use the context menu of alert. Each of the message belongs to different alert classes.
Example − An alert can have different class that shows different status messages.
Class 1 − Termination Messages
Class 2 − Error Messages
Class 3 − Warning Messages
Class 4 − Success Messages
Order Related PP/DS Alerts
Following PP/DS alerts are raised w.r.t orders raised −
- Alerts for the orders with status deallocated
- Alerts for orders with date time in the past
- Quantity falls short/exceeds desired quantity
- Order with validity period expired
PP/DS Alerts Related to Resources
In PP/DS, you can have alerts raised related to resources in planning.
- Alerts related to resource utilization above/beyond threshold value
- Capacity overload for bucket resource
- Resource overload in case of single/multi-activity resource
- Alerts related to container resources planning
PP/DS Alert for Campaigns
Following PP/DS alerts can be raised related to campaign planning. When planning with production campaign is performed, the system can issue following alerts −
- Alerts related to cleanout order in a campaign
- Alerts related to interrupted campaign

Master data can be created in relevant component of SAP APO or you can also transfer it from SAP R/3 to SAP APO. It can be transferred using Core Interface (CIF) to SAP APO module.
In master data integration model, you define the master data transfer to SAP APO module. Following master data can be transferred −
- Material (Product)
- Plant (Location)
- Customer (Location)
- Work Center (Resource)
- Vendor (Location)
In SAP APO, all the master data that has been transferred can be checked. When an error occurs, you can also check the application logs.
To check application logs, navigate to SAP Easy Access → SAP APO → APO Administration → Integration → Monitor → Application Log → Display Entries.
Select Object Id, sub-object Id, time restrictions, log class, log source, and formatting.
Location Master Data
Location shows the place where products or resources are managed. You can create, change or display the master data related to locations.
To create, change, or display master data navigate to SCM Basis → Master Data → Location → Location Master Data Home Screen.
In the next window, enter Location number and Location Type.
To display master data, click the Display button at the bottom of the screen. You can select Change/Create button accordingly. When you click Display, it shows you all the tabs in the location master data.
Deleting a Location
To delete a location, you need to set up the deletion flag on the home screen. Deletion can be performed in the background process.
Click the Save button.
Application Log for Location Master
Application logs are used to manage data related to events, errors, and warnings related to Location master data. You can save the logs, display it from the database or delete the logs. Application logs helps to provide −
- Basic information
- Long text of the message
- Detailed information through the log files
- Technical information
To display Application log, you have to navigate to SCM Basis → Master Data → Location → Application Log → Display Application Log.
In the next window, you have to enter the user name, time restriction, and the number of logs restriction. Click the Execute button or press F8.
To delete the logs, navigate to SCM Basis → Master Data → Location → Application Log → Delete Application Log.
Product Master Data
You can find product master data under SCM basis and this data can be used in all applications such as SAP APO. Product Master Data is maintained under Master data in SCM Basis. You can add, display, change, or delete products.
Product Master of SCM can be used in other master data like locations or documents. You can maintain the following Global Product master and location specific product master.
Global Product Master
Navigate to SCM Basis → Master Data → Product.
In Product Master Initial screen, you have the view option and profile definition option. You have to select Global data to maintain Global product master. When you select Location under View option, it opens the location product master.
