What is Advanced Planning and Scheduling (APS) :

SAP Advanced Planning and Scheduling (APS) in SAP ABAP refers to a set of functionalities and tools used to optimize and automate production planning and scheduling processes within the SAP system. APS solutions aim to improve efficiency, reduce costs, and enhance customer service by ensuring that production resources are utilized effectively and production schedules are aligned with demand and capacity constraints.

 In SAP, APS functionalities are often implemented using various modules and components within the SAP ERP system, such as Production Planning and Control (PP), Materials Management (MM), and Advanced Planning and Optimization (APO). SAP APO, in particular, provides advanced planning and scheduling capabilities that complement the standard SAP ERP functionalities.

What are the advantages of Advanced Planning and Scheduling (APS)

Efficient Resource Utilization: APS helps in optimizing resource utilization by scheduling production processes based on available resources like manpower, machinery, and raw materials. This ensures that resources are used efficiently, minimizing idle time and reducing costs.
Improved Production Planning: APS enables better production planning by considering various factors such as demand forecasts, inventory levels, lead times, and capacity constraints. This results in more accurate production schedules, reducing the risk of stockouts or overproduction.
Enhanced Visibility: APS provides real-time visibility into the entire production process, from order entry to delivery. This visibility helps in identifying potential bottlenecks and allows for proactive decision-making to avoid disruptions and delays.
Optimized Inventory Levels: By synchronizing production schedules with demand forecasts, APS helps in maintaining optimal inventory levels. This prevents excess inventory buildup, reduces carrying costs, and ensures that products are available when needed.

• Shorter Lead Times: APS streamlines production processes and reduces lead times by eliminating inefficiencies and delays. This enables businesses to respond more quickly to customer demands and market changes, improving overall competitiveness.
Better Customer Service: With APS, businesses can fulfill customer orders more efficiently and reliably, leading to higher customer satisfaction and retention. By delivering products on time and in the right quantities, businesses can build stronger relationships with customers and gain a competitive edge in the market.
Integrated Planning: APS can be integrated with other SAP modules such as Sales and Distribution (SD), Materials Management (MM), and Production Planning (PP), allowing for seamless data exchange and collaboration across different departments. This integration ensures that planning decisions are based on accurate and up-to-date information, leading to better outcomes.

What are the Features of:

• Cost reduction
• Improved customer service level
• Integration with SAP ERP Modules
• Capacity Planning:
• Fast reaction to market changes
• Production Scheduling Algorithm
• Real-time Monitoring and Reporting
• Material Requirements Planning (MRP)
• User Interface Customization
• Optimization and Performance Tuning


APS being implemented in TEPL, Advanced planning and scheduling (APS) refers to a manufacturing management process by which raw materials and production capacity are optimally allocated to meet demand.


Using SAP ECC and SAP PI/PO, synchronous SOAP interface construction was created. APS will use a WSDL connection to consume the interface. The SAP system will process the request from the APS side and respond by sending the requested data back to the APS.

Here are a few developed interfaces:

1. Create PR from APS data: 

Create PR’ Interface will provide dynamic Purchase Requisition creation for any given Purchase Requisition Document Type. Item number of PR, Material Number, Plant, Storage location, Quantity moved in GR/GI, PR unit of measure, Delivery Date.
Creating a Purchase Requisition interface functional module in SAP ABAP involves designing a user-friendly interface, developing a custom function module for PR creation, implementing PR creation logic, error handling, and thorough testing.
This enables organizations to streamline the process of creating PRs and improve efficiency in procurement operations.

2. Open Purchase Orders:

Open Purchase Order’ Interface will provide list of all open purchase order for given any PLANT and from, to date.

By implementing an Open Purchase Order interface functional module in SAP ABAP, organizations can streamline and automate the process of generating Open POs, thereby enhancing efficiency in procurement operations.

This approach facilitates seamless integration between external systems and SAP, leading to improved productivity and accuracy in PO management.

3. Open PR from SAP to APS:

‘Open Purchase Requisition’ Interface will provide list of all open purchase requisition for any given PLANT.

developing an Open Purchase Requisition (PR) interface functional module in SAP ABAP provides organizations with a powerful tool to streamline and automate their procurement processes.

4. Open Planned Order:

‘Open Planned Order’ Interface will provide list of all open purchase Planned for any given PLANT, From Date and To Date.

the development of an Open Planned Order interface functional module empowers organizations to optimize their production planning operations, enhance efficiency, and drive value across the production lifecycle.

5.Create Planned Order:

Create PO Interface will provide dynamic Purchase Order creation for any given Purchase Order Document Type. Planned Order Profile, Material, Planned Plant, Production Plant, Total Planned Order Plant, Order State Date, Order State end, Storage Location and MRP area.

6. Open Production Order
‘Open Production Order’ Interface will provide list of all open production Order for any given PLANT.
