SAP MM is excellent as a system of record — but store operators often need simpler screens, faster search, and workflows ERP was never designed to optimize. The answer is not replacing SAP; it is building controlled custom layers that read and write through clear rules.
Pattern 1: Read-heavy operational dashboards
Custom web apps pull MM stock, vendor, and movement data for floor teams while SAP remains authoritative. Writes happen through defined interfaces or batch jobs — not ad hoc spreadsheet imports.
Pattern 2: Spreadsheet bridge retirement
Many plants run parallel Excel systems because MM screens are slow. We migrate one workflow at a time — requisitions, tool issues, cycle counts — into web apps with validation before data touches SAP.
Pattern 3: Agents for exception handling
AI agents monitor integration queues, flag stale PO lines, and summarize what needs human action — reducing the admin burden on MM power users.
