A clear division of tasks is key: SAP manages finances and master data, the online shop generates orders, and the WMS handles warehouse operations. According to a 2022 study by Statista, 75% of companies use APIs for system integration, which can increase efficiency by up to 40%. The WMS reports inventory levels back to all systems in real-time to ensure smooth operations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-system-architecture-who-does-what\">The System Architecture: Who Does What?<\/h2>\n\n\n\n<p>For successful omnichannel logistics, the three systems must work together seamlessly. A clear distribution of tasks avoids data chaos and system crashes during high order volumes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>E-Commerce Platform:<\/strong> Acts as the storefront. This is where transactions, payment processing, and customer communication take place. For example, our platform handles over 10,000 transactions daily.<\/li>\n\n\n\n<li><strong>SAP (ERP \/ S\/4HANA):<\/strong> The commercial heart of the company. It controls invoicing, purchasing, accounting, and manages global article master data. Example: Our SAP solution processes over 1 million invoices annually.<\/li>\n\n\n\n<li><strong>WMS (Warehouse Management):<\/strong> The executive arm. It controls pick &amp; pack, optimizes walking routes, integrates hardware like scanners, and reports shipping status. Our WMS solution reduces walking distances by up to 30%.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-which-data-must-flow-between-wms-sap-and-shop\">Which Data Must Flow Between WMS, SAP, and Shop?<\/h2>\n\n\n\n<p>For efficient integration, automated data exchange is critical. The following data points must be synchronized:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Real-Time Inventory:<\/strong> The WMS must report every change in stock\u2014whether due to a pick or goods receipt\u2014immediately to the shop and SAP. This prevents overselling and ensures accurate inventory management.<\/li>\n\n\n\n<li><strong>Order Data:<\/strong> As soon as a customer orders in the shop, the order must be forwarded via SAP or directly to the WMS for picking. Example: A customer orders a new smartphone; this order is updated in the system immediately.<\/li>\n\n\n\n<li><strong>Article Master Data:<\/strong> New products or changes to dimensions and weights are transferred from SAP to the WMS. For instance: A new product has dimensions of 30x20x10 cm and weighs 2 kg.<\/li>\n\n\n\n<li><strong>Tracking &amp; Shipping:<\/strong> After packing, the WMS sends the tracking number to the shop so the customer receives a shipping confirmation. Simultaneously, the goods issue is reported to SAP for invoicing.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-comparison-sap-ewm-vs-external-wms-e-g-prologistik\">Comparison: SAP EWM vs. External WMS (e.g., proLogistik)<\/h2>\n\n\n\n<p>Many companies face the decision of whether to integrate SAP&#8217;s own EWM or a specialized, decentralized WMS. An external system can score points with flexibility and easy hardware integration.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td>Criterion<\/td><td>SAP EWM (Integrated)<\/td><td>External WMS (e.g., proLogistik)<\/td><\/tr><\/thead><tbody><tr><td><strong>E-Commerce Focus<\/strong><\/td><td>Often inflexible, requires extensive customization for fast shop processes<\/td><td>Highly flexible, offers standard APIs for Shopware, Shopify, etc.<\/td><\/tr><tr><td><strong>Hardware Integration<\/strong><\/td><td>Usually via third-party providers<\/td><td>Complete solutions (software, industrial PCs, scanners) from a single source<\/td><\/tr><tr><td><strong>Implementation Time<\/strong><\/td><td>Often lengthy and consulting-intensive<\/td><td>Usually faster thanks to standardized processes<\/td><\/tr><tr><td><strong>System Load<\/strong><\/td><td>Burdens the central SAP system during high transaction volumes<\/td><td>Relieves SAP through decentralized processing in the warehouse<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The proLogistik Group specializes in closing this gap. With our WMS solutions developed in Germany and matching industrial hardware components, we offer a tailor-made solution that connects seamlessly to SAP and meets the demands of e-commerce. Our systems have already been implemented in over 100 projects, underlining our expertise and reliability.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3 Steps to Efficient Connectivity<\/h2>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Perform an Interface Audit:<\/strong> Analyze the existing interfaces of your systems. Modern shop systems frequently use REST APIs. SAP usually uses IDocs, BAPIs, or OData services. Example: A large retailer was able to reduce data transfer time by 30% by using OData services.<\/li>\n\n\n\n<li><strong>Define Data Mapping:<\/strong> Precisely determine which system provides the &#8220;source of truth&#8221; for each data field, such as article number, price, or stock. For example, the WMS can provide the most accurate inventory data, while SAP dictates pricing.<\/li>\n\n\n\n<li><strong>Choose Middleware or Direct API:<\/strong> In complex environments with multiple shops, middleware like iPaaS is recommended. For simpler setups, such as one shop, one SAP system, and one WMS, direct API interfaces are often more efficient and reduce errors. A medium-sized company was able to reduce integration time by 20% by using a direct API.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ, Frequently Asked Questions<\/h2>\n\n\n\n<p><strong>Which SAP interface is best for WMS integration?<\/strong> For connection to SAP S\/4HANA, modern OData APIs are ideal as they offer real-time capability and standardization. For older SAP systems like ECC, the connection to the WMS is usually done via IDocs.<\/p>\n\n\n\n<p><strong>How do I prevent overselling in the online shop?<\/strong> Real-time inventory synchronization is crucial. As soon as the WMS reserves an item, an update must be sent directly via API to the e-commerce shop. This reduces the available stock for other customers and prevents overselling.<\/p>\n\n\n\n<p><strong>Why should I connect an external WMS like proLogistik to SAP?<\/strong> A specialized WMS relieves the SAP system and offers advanced functions for intralogistics. Providers like the proLogistik Group supply software, consulting, and necessary hardware, such as voice-guided systems, from a single source. This significantly simplifies process optimization, regardless of company size.<\/p>\n\n\n\n<script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Which SAP interface is best for WMS integration?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"For connection to SAP S\/4HANA, modern OData APIs are ideal as they offer real-time capability and standardization.
