EDI customer connections for outgoing messages in the course of a company merger

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.
