SAP Next-generation Just-In-Time Supply to Production
Introduction

In the modern, fast-paced manufacturing world, companies strive to optimize their processes for efficiency, cost-saving, and customer satisfaction. SAP’s next-generation Just-In-Time (JIT) Supply to Production provides an integrated solution that allows manufacturing entities to streamline their production processes, reduce inventory costs, and ensure that the right components arrive just when needed. Let’s dive into this state-of-the-art solution.

What is SAP Just-In-Time Supply to Production

SAP Just-In-Time Supply to Production is an innovative approach designed for manufacturing setups that thrive on JIT principles. With the challenges posed by varied customer demands and limited storage space, manufacturers need a sophisticated solution. The SAP JIT ensures that components, whether sourced externally or from internal warehouses, are delivered in the right quantity and at the precise moment they’re needed for production, ensuring optimal workflow and reducing unnecessary inventory overhead.

JIT-Process Architecture
This architecture represents a flowchart detailing the Just-In-Time (JIT) Supply to Production process in an SAP environment. The diagram shows how various components and functionalities of SAP interrelate, especially in the context of materials management, production planning, logistics execution, and transportation. Let’s break it down:

Production Planning:

The process begins with “Production Order (PP)”, which may derive from a “Planned Order” either from PP-REM or PPDS.

These planned orders create demands for either JIT (Just-In-Time) or JIS (Just-In-Sequence) processes.

JIT Supply to Production:

Master data and communication group management are fundamental components.

The control cycles of JIT are managed and modified, leading to various processes like JIT call management, planning of supply to production, scheduling of JIT replenishments, and more.

The JIT calls, whether summarized or sequenced, influence the internal replenishment processes and stock transfers.

OEM/Customer (Original Equipment Manufacturer):

This section provides an overview and analytics of the JIT supply to production, highlighting potential changes in the plan and monitoring of JIT calls and their components.

Materials Management:

This is where scheduling agreements and schedule lines come into play. As materials are planned and ordered, updates to quantities (Qty Updates) are made, which then lead to the creation of various logistics and transportation processes.

Logistics Execution:

Before the goods are received, there’s a series of actions such as updating status, delivery creation, setting transfers, and eventually posting the goods receipt.

This interacts closely with the Transportation Management and Warehouse Management processes.

Transportation Management:

The system manages the transportation of goods via various stages like creating consignment orders, assigning freight units, managing freight orders, and handling advanced shipping & receiving protocols. External replenishments might also be noted via SOAP messages.

Extended Warehouse Management:

Once goods are in the warehouse, processes like pick/prepare management, route train loading, and pick execution are carried out. Internal replenishments are managed, and unloading points for goods are defined.

The production supply areas and storage bins for different production lines are clearly depicted.

Integration Points:

Red dotted lines typically signify integration or informational flow between processes.

Green solid lines might indicate a direct flow or process sequence.

Storage and Stock Management:

The architecture demonstrates the flow of stock and its management, transitioning between IM-managed source storage locations, destination areas, and EWM-managed areas.

In essence, this architecture provides a holistic view of how JIT supply to production processes are executed within the SAP environment, integrating production planning, materials management, logistics, transportation, and warehouse management for efficient and streamlined operations.

Inbound Vs Outbound JIT
Introduction

Have you ever wondered about the intricate dance of products and materials moving in and out of a manufacturing facility? It’s not just a matter of stocking up and shipping out. In the world of Just-In-Time (JIT) manufacturing, the flow is finely tuned to perfection. Let’s delve deeper into the realm of Inbound and Outbound JIT, and see how they differ from each other.

Inbound JIT

Imagine a bustling car manufacturing plant. Now, instead of having months’ worth of parts stocked up in a warehouse, the facility gets its components delivered just when they’re about to be used in production. That’s Inbound JIT for you.

Inbound JIT focuses on the timely delivery of materials and parts from suppliers to the manufacturing facility. It’s all about reducing storage costs, minimizing the space required for inventory, and ensuring that parts are fresh off the delivery truck and straight into production. This methodology requires a strong and reliable relationship with suppliers. The idea is to have components arrive not a moment too early or a second too late.

Outbound JIT

Now, let’s flip the script. Once our cars are assembled, they don’t just pile up waiting for someone to buy them. Outbound JIT is all about ensuring that the finished products are delivered to dealerships or end customers precisely when they’re needed.

Instead of producing large quantities of products and then finding customers for them, manufacturers relying on Outbound JIT produce based on actual demand or close forecasts. This means lower storage costs for finished products and faster delivery times. It’s about ensuring that the time from the end of the production line to the customer’s driveway is as short as possible.

Inbound Vs Outbound JIT

At first glance, Inbound and Outbound JIT might seem like two sides of the same coin. And in a way, they are. Both revolve around the concept of ‘just in time’ – minimizing storage and maximizing efficiency. But here’s the difference:
- Focus: While Inbound JIT is concerned with materials coming into the production line, Outbound JIT focuses on getting the finished product out to the customers efficiently.
- Relationships: For Inbound JIT, the manufacturer’s relationship with its suppliers is crucial. Reliable and timely deliveries are the name of the game. On the other hand, Outbound JIT is more about understanding customer demand and ensuring that production schedules align with it.
- Benefits: Both methods aim to reduce storage costs. Inbound JIT ensures fresher components and minimizes the risk of inventory obsolescence. Outbound JIT, meanwhile, ensures that finished products don’t languish in storage, which can be particularly vital for products that are time-sensitive or have short shelf lives.
When the influx of raw materials and parts are made within supplier and manufacturing plants then it involves Inbound JIT. When the movement of final goods is made from supplier to end users, then it involves Outbound JIT. Read more about Inbound Delivery and Outbound Delivery.

In conclusion, while both Inbound and Outbound JIT share a common philosophy, their applications are distinct yet complementary. In the finely-tuned ballet of modern manufacturing, both play essential roles in ensuring that companies remain efficient, responsive, and cost-effective. And that, my friend, is the magic of JIT in action!

Just-In-Time (JIT) and Just-In-Sequence (JIS) Processing in SAP S/4HANA
Introduction

The automotive industry is all about speed, precision, and meeting customer needs. A significant part of this involves ensuring that components are available exactly when they’re needed, and in the correct order. This is where Just-in-time (JIT) and Just-in-sequence (JIS) processing come into play. Today, we’re diving into how SAP S/4HANA, a leading enterprise resource planning software, is revolutionizing this process.

What is Just-In-Time (JIT)?

JIT, or Just-In-Time, is a production method rooted in the principle of reducing in-process inventory. Given the sheer variety of configurations automotive manufacturers offer, there’s a need to have a multitude of components on hand. However, with space at a premium on production lines, it’s crucial to keep inventory lean. This means having suppliers or internal warehouses deliver small quantities of components multiple times a day. In a JIT environment, the sequence in which these parts are delivered doesn’t matter.

Just-in-Time inventory, commonly referred to as JIT, is an inventory management strategy in which raw materials arrive as soon as production is scheduled to begin but no sooner. The goal is high-volume production with minimal inventory on hand to meet demand and eliminate waste.

What is JIT in SAP?

JIT calls in SAP are created for a supplier based upon demands that can be either planned or production orders and even based upon the safety stocks in case of consumption-driven scenarios.

SAP provides multiple T-Codes to manage the JIT scenarios. SAP has also introduced Fiori Apps to manage JIT for S/4 HANA customers.

It is important to note that JIT is a very complex process as it highly depends upon the efficacy of the ordering system so that items are delivered with the right amount at the right time.

SAP JIT Types

Based on scenarios JIT can be divided into two structures
- JIT Supply to Customer: Also, known as JIT S2C covers the JIT processes from the perspective of a supplier.
- JIT Supply to Production: Also, known as JIT S2P covers the JIT processes from the perspective of Manufacturers.
JIT in R/3 ABAP

SAP on-premise system provides all the methods that can be used to maintain a plan, create scheduling agreements, create a JIT order, plan a JIT forecast order, and many other relevant operations. Various Reports and T-codes are available to create and manage the same such as:

JIT in S/4 HANA

SAP S/4 HANA provides various Fiori Apps that can be used to create, manage and plan a JIT. Different Apps provide different functionality. The technologies involved for the same include ABAP CDS, BOPF, ABAP RAP, and Fiori.

What is Just-In-Sequence (JIS)

Unlike JIT, Just-In-Sequence (JIS) focuses on delivering the right components to the production line in the exact sequence they are needed. This becomes especially crucial when suppliers are building complex modules or sets that are directly delivered to the line.

Just-In-Time (JIT) and Just-In-Sequence (JIS) Processing in SAP S/4HANA

SAP S/4HANA has risen to the occasion, offering next-gen JIT and JIS processing, catering to both automotive manufacturers and their wider ecosystems. It provides support for both summarized JIT calls and sequenced JIT calls from both outbound and inbound perspectives.

JIT Supply to Production

Delving deeper into the JIT Supply to Production, we see a demand-triggered pull signal to either internal or external supply sources. The highlights of this process include:
- Flexibility: You can cater to both summarized and sequenced JIT calls.
- Integration: Seamless linkage with SAP S/4HANA inventory management and SAP Extended Warehouse Management (SAP EWM) means tasks can be directly created in embedded EWM.
- Adaptability: Reordering of sequenced JIT calls in case of damage or quality issues is possible, ensuring production isn’t halted.
- Real-time Transparency: With embedded analytics, companies can have an instant overview of their operational system, facilitating better decision-making.
What’s more, the use of communication groups for multiple JIS call recipients and lifecycle management for control cycles ensures that this system can be tailored to fit specific customer needs.

JIT Supply to Customer

Switching gears to JIT Supply to Customer, we find a similarly robust system. Key takeaways here include:
- End-to-End Process Support: With both summarized and sequenced JIT calls being supported, companies have a comprehensive toolkit at their disposal.
- Flexibility: Rules-based component group determination, combined with simplified grouping of sequenced JIT calls, allows for precise and efficient packing and delivery.
- Usability: The new SAP Fiori user interface, combined with a monitoring app for JIT calls, ensures that the system is both powerful and user-friendly.
- Transparency: Thanks to SAP S/4HANA’s embedded analytics, companies can get a clearer view of their stock availability and demand analysis.
In essence, SAP S/4HANA’s next-gen JIT solutions elevate the JIT processing, offering automotive companies the tools they need to streamline processes, enhance reliability, and ultimately, boost customer satisfaction.

In conclusion, as the automotive world becomes more complex and customer-centric, systems like SAP S/4HANA’s JIT and JIS processes will be the linchpin holding production lines together, ensuring that the right part is always at the right place, at the right time.
