In this article you\u2019ll get a clear explanation of what Clean Core is, why it matters now and ahead, and how you can start <s> <\/s> the journey. <\/p>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h3 class=\"wp-block-heading\" id=\"h-clean-core-forandringen-sap-vill-att-du-tar-pa-allvar-nbsp\"><strong>Clean Core: the change SAP expects you to take seriously<\/strong> <\/h3>\n\n<p>Over decades, ERP systems have become increasingly complex and heavily customized. Tailored code, altered standard flows and advanced integrations have led to what SAP itself refers to as \u201ctechnical debt\u201d. The result? Escalating maintenance costs, delayed and risky upgrades \u2014 and difficulty embracing new innovation. In short: you fall behind both technically and commercially.     <br\/><br\/>With SAP Clean Core the paradigm shifts. Instead of building in the core, you build around it or side\u2011by\u2011side. With standard as a foundation, documented APIs and business logic relocated out from the ERP into side modules, your ERP becomes not just faster to upgrade \u2013 it becomes an enabler for innovation and rapid change.   <\/p>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h3 class=\"wp-block-heading\" id=\"h-vad-innebar-clean-core-i-praktiken-nbsp\"><strong>What does Clean Core look like in practice?<\/strong> <\/h3>\n\n<p>Clean Core is a broad concept that addresses many dimensions of an SAP system. <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Upgrade\u2011ready and documented functional development built on standard technology and best practices<\/li>\n\n\n\n<li><strong>Integrations<\/strong> that are upgrade\u2011safe, documented and stable in terms of monitoring and operations.<\/li>\n\n\n\n<li><strong>Processes<\/strong> built on SAP Best Practice and connected end\u2011to\u2011end.<\/li>\n\n\n\n<li><strong>Data<\/strong> of high quality, complete, and used as intended.<\/li>\n\n\n\n<li><strong>Daily operations<\/strong> that support the above principles, with scheduled maintenance windows and proactive monitoring &amp; actions. <\/li>\n<\/ul>\n\n<p>In this article, we focus specifically on how companies can build and manage additions to standard ERP functionality. It&#8217;s primarily about: <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Keeping the SAP S\/4HANA core as structured as possible. <\/li>\n\n\n\n<li>Avoiding modifications to standard functions whenever possible. <\/li>\n\n\n\n<li>Create business logic outside the core by utilizing tools in SAP Business Technology Platform.  <\/li>\n\n\n\n<li>Use APIs and develop event-driven integrations. <\/li>\n\n\n\n<li>Structure data so that master data can be reused and managed centrally. <\/li>\n<\/ul>\n\n<p>It&#8217;s not just about technology. Clean Core requires a shift in culture, governance, and architectural philosophy. As described above, SAP itself highlights five dimensions: processes, extensions, integration, data, and oper<g id=\"gid_0\">a<\/g>tions. All must be addressed.    <\/p>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h3 class=\"wp-block-heading\" id=\"h-darfor-ar-clean-core-avgorande-i-dagens-erp-landska-p\"><strong>why Clean Core is Crucial in Today&#8217;s ERP Landscap<\/strong>E<\/h3>\n\n<p>SAP&#8217;s investment in cloud solutions, automatic upgrades, and AI solutions relies on customers keeping their systems updated. If ERP is a &#8220;black box&#8221; full of old code and unknown dependencies, you cannot:  <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Receive new functionality from SAP. <\/li>\n\n\n\n<li>Upgrade without extensive testing projects. <\/li>\n\n\n\n<li>Leverage SAP Business Technology Platform, AI, and automation. <\/li>\n\n\n\n<li>Build a flexible architecture with sustainable cost structure. <\/li>\n<\/ul>\n\n<p><br\/>Unlike classic on-prem systems, SAP&#8217;s SaaS solutions are built with limited direct code customization capabilities. As a result, customer-unique and business-critical needs must be handled in new, more sustainable ways \u2013 outside the core. CIOs and architecture leaders facing a cloud transformation are at a crossroads: <strong>continue patching and fixing \u2013 or structure for the future.<\/strong>    <\/p>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h3 class=\"wp-block-heading\" id=\"h-vanliga-utmaningar-pa-vagen-mot-clean-core-nbsp\"><strong>Common Challenges on the Path to Clean Core<\/strong> <\/h3>\n\n<p>A few obstacles typically emerge: <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Legacy code and dependencies are often poorly documented. <\/li>\n\n\n\n<li>The business wants to retain its &#8220;customized advantages&#8221; <br\/>i.e., focus on what&#8217;s being lost. <\/li>\n\n\n\n<li>IT departments lack time, tools, or expertise. <\/li>\n\n\n\n<li>Insufficient governance allows old patterns to persist. <\/li>\n<\/ul>\n\n<p>As <a href=\"https:\/\/www.linkedin.com\/in\/eero-koskinen-1968may\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Eero Koskinen<\/strong><\/a> Enterprise Architect SAP points out in Implema Talks \u2013 <strong><a href=\"https:\/\/youtu.be\/dm5uAa4tSOY?si=X2Hcrq7oIwXbxX0u\" target=\"_blank\" rel=\"noopener\">Why Clean Core matters for SAP and your business<\/a><\/strong>: <\/p>\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><em>&#8220;Clean Core is as much about architecture and governance as it is about code.
