Senior consultant Martin Humberg explains the origin of the challenge: the Innogy\u2013E.ON merger left around 17 legacy ERP systems with different master data and charts of accounts, making cross-company business and reconciliation painfully slow. Consolidating onto a single system with harmonized master data changed daily operations \u2014 enabling group-wide procurement scale, easier reporting, and faster, more precise financial close for the stock market.<\/p>\n<p>\u201cWe cut migration downtime from three or four days to just two six-hour windows \u2014 a genuine business enabler for 46,000 users.\u201d<\/p>\n<p style=\"font-size: 1rem; margin: 0;\">By running cloud migration, master data harmonization, and process redesign as one concurrent program rather than sequential streams, E.ON compressed a six-year journey and captured real synergies. SNP\u2019s Kyano Crystal Bridge moved enormous volumes of data across systems in Poland, Sweden, and Germany, while a minimized-downtime approach with staging areas kept 46,000 users productive during cut-over. The result is a harmonized platform that supports AI-driven processes and E.ON\u2019s reinvention from a traditional network operator into a data-driven digital services company.<\/p>\n<p style=\"font-size: 11px; font-weight: bold; letter-spacing: 0.14em; text-transform: uppercase; color: #f26522; margin: 0 0 18px 0;\">About the Guest<\/p>\n<p><img decoding=\"async\" style=\"width: 110px; height: 110px; object-fit: contain; border-radius: 50%; display: block; background: #f4f3f0; padding: 16px; box-sizing: border-box;\" src=\"https:\/\/www.europesays.com\/germany\/wp-content\/uploads\/2026\/07\/cropped-cropped-cropped-Logo_Black-1.png\" alt=\"ERP Today\"\/><\/p>\n<p>Martin Humberg<\/p>\n<p style=\"font-size: 0.78rem; font-weight: bold; letter-spacing: 0.05em; text-transform: uppercase; color: #f26522; margin: 0 0 12px 0;\">Senior Consultant, E.ON<\/p>\n<p style=\"font-size: 0.95rem; color: #333; line-height: 1.7; margin: 0;\">Martin Humberg is a Senior Consultant at E.ON, where he has been a key figure in the energy industry\u2019s largest-ever SAP S\/4HANA project \u2014 consolidating 500+ companies and 17 legacy ERP systems onto a single harmonized platform with SNP.
