The EDI connection of customers for sending electronic order confirmations, delivery notifications and invoices to support the e-commerce department of a paper merchant in the course of the merger of two companies is realised. The EDI connection of customers for electronic outgoing messages serves as an important step towards digitalisation in form of process automation and consolidation of the respective company-specific processes.
The electronic order confirmations, shipping notifications and invoices are transferred from the SAP S/4HANA merchandise management system in IDoc format to a middleware (web application developed individually by the customer). The web application performs checks and transfers the IDocs via web service to another middleware, 'Lobster_data'. There, a Lobster mapping (profile) receives the IDocs, checks them and converts them into a standardised format (IDoc) for all customers. On the basis of a customer identifier supplied in the IDoc, which is known to both middleware systems, a decision is made as to which customer-specific profile is called up, which then generates the target format expected by the customer and transfers it to the recipient (buyer) in a previously agreed way (e.g. FTP, e-mail). In addition to interface coordination with the e-commerce department, the technical implementation in 'Lobster_data' is an important focus of activity in the project.
The work is carried out for the customer's IT department on behalf of the e-commerce department. The e-commerce department provides technical and organisational support for the EDI connections to support its own sales department and its end customers. From the SAP S/4HANA merchandise management system via the web application, the data to be sent to the goods orderers (IDocs ORDRSP, DESADV, INVOIC02) is transferred to the 'Lobster_data' tool, where the outgoing EDI messages are generated and sent to the goods orderers in the format expected there (e.g. XML, EDIFACT) under strong process standardisation.
