SAP JIT/JIS – Efficient Just-in-Time and Just-in-Sequence Processes in Logistics

[Vitaly_Toraman]

Just-in-Time (JIT) and Just-in-Sequence (JIS) processes play a crucial role in the modern manufacturing and automotive industries. They ensure optimized material supply, reduce storage costs and enable smooth production. SAP offers comprehensive support for these processes with its modules - but in practice it turns out that hardly any company uses a pure SAP standard solution. Instead, there are usually customer-specific adaptations that are similar in their basic principle

JIT and JIS – The fundamental difference

Just-in-Time (JIT) ensures that materials are delivered exactly when they are needed in production. This significantly reduces inventory levels and increases flexibility. Just-in-Sequence (JIS) goes a step further: Here, materials are not only delivered on time, but also in the order in which they must be used directly in production or assembly. This is particularly essential in the automotive industry, where specific components must be provided at exactly the right time and in the right order.

Just-in-Sequence (JIS) goes one step further: Here, the materials are not only delivered on time, but also in the order in which they must be used directly in production or assembly. This is particularly essential in the automotive industry, where specific components must be provided at exactly the right time and in the right order.

SAP JIT/JIS in Practice

SAP offers solutions for these processes in the area of ​​SAP S/4HANA Supply Chain Management , especially in the SAP JIT Inbound Processing module . However, the implementation approach varies depending on the customer:

• Customer-specific EDI connections : Delivery schedules, detailed delivery schedules and ASN messages are often individually designed to meet the specific requirements of the company and its suppliers.
• Tailor-made sequence controls : Many companies use their own logic for sequence planning because the SAP standard does not always cover all industry-specific requirements.
• Integration with production systems : JIT/JIS processes must interact seamlessly with MES (Manufacturing Execution Systems) or other manufacturing systems.

Why experience is crucial

Since each implementation requires individual adjustments, experience with different JIT/JIS solutions is essential. An experienced consultant can:
Quickly analyze processes and identify the similarities and differences to other customer solutions.
Incorporate best practices from previous projects to develop an efficient and future-proof solution.
Minimize the risk of errors by identifying typical stumbling blocks (e.g. incorrect sequencing or unstable EDI connections) at an early stage.

Conclusion

JIT and JIS processes are complex, but their successful implementation ensures a significant increase in efficiency in production. The SAP standard forms a solid basis, but in practice customer-specific adaptations dominate. Here, experience counts above all - it makes the difference between a functional and a truly optimized solution.
