Once upon a time, back in the s, there was a little red Volkswagon Beetle. This VW bug, as it was affectionately known, was owned by an uncle of mine. My uncle loved his little red bug and kept it for more than 14 years. He drove it everywhere … in his daily life, on weekends, vacations that took him coast-to-coast in the United States, clear across Canada, and deep into Mexico. And over time it developed a host of mechanical and structural ills, including holes in the floors on both the driver and passenger sides, just like in the Flintstones.

Introduction The supply chains of automotive companies are usually fully automated. Instead of using paper-based processes, OEMs original equipment manufacturers and their suppliers communicate using electronic data interchange EDI.
Thereby, messages are sent from one IT system to another IT system without any human intervention. In the following article we examine the most important EDI processes in an automotive supply chain. Overview of automotive processes The following Figure gives a brief overview of document types, which are being exchanged between an OEM, its tier 1 suppliers and the tier 2 suppliers.
The process automation may of course also include tier 3 suppliers, tier 4 suppliers, etc. Click here for a high resolution version of the image. Using a forecast message an OEM communicates the demand for a specific part to the supplier.
Thereby, a forecast message usually contains the weekly demand for up to 52 weeks. The further in the future, the less exact are the forecasted values. Nevertheless, the forecast gives the supplier a good decision basis to calculate his own demands. Oftentimes the JIT forecast also contains additional information such as the exact unloading point, where the goods shall be shipped to or delivery timeframes in which the goods must be delivered to the OEM.
These forecasts are used to communicate the exact sequence in which certain parts must be delivered to the OEM. After a supplier has dispatched the goods from his production site, he must issue an ASN advanced shipping notice message.
Usually, the ASN contains information about pallets, the number of used boxes, the used serial numbers for pallets and boxes and so on. The serial numbers are also attached as labels to the pallets and boxes. Thereby, any deviations in the delivered goods may easily be recognized and the necessary actions may be taken.
Depending on whether the ASN could be successfully processed by the OEM or not, the supplier receives a positive or a negative acknowledgement. Using a receipt advice, the OEM communicates back to the supplier how many delivered goods were received. Finally, the payment details are communicated either using a credit note or an invoice message. Instead there are different standardization organizations, issuing different standard versions. In the following we dwell on the most important ones.
The standard per se is quite verbose and almost never used in its plain version. Instead different industries and companies have defined their own subsets of the generic standard. The subcommittees of ANSI develop EDI standards for various industries and domains such as finance, transportation, insurance, supply chain, etc. Among other activities VDA issues a set of EDI standards, which are used for the exchange of business documents along the automotive supply chain.
VDA is widely used among German car manufacturers and their suppliers. Odette Odette International Ltd. The goal of Odette is to achieve consensus solutions for the various challenges in the automotive industry, thus, ensuring maximum efficiency of supply chain processes.
Mapping to IDoc types In the following we provide a comparison table, showing the different EDI message formats and types, which may be employed for the processes in the automotive supply chain.
Note, that the basic type and the message type of an IDoc may be different, depending on the used SAP version and the application scenario. Depending on the business partner and the global location, one may encounter a multitude of different EDI standards and standard versions. The EDI converter solution may either run locally e.

The rigour with which each assembly phase is carried out depends to a great extent on the effectiveness of communications between the different partners involved in the supply chain. The aim is to make the information exchange more efficient, improving the needs of OEMs Original Equipment Manufacturers. There are currently two trends in the automotive industry. On one hand, standardization of VDA messages, for which new versions have been rolled out, and on the other, the incorporation of lower-level suppliers to the information flow, to ensure traceability and the seamless exchange of information through EDI systems. Standardization of VDA messages VDA messages are the EDI messages used in the automotive sector and which meet the specific needs of companies in the automotive industry.
