Frequently asked questions
What is SAP master data governance?
The ownership, validation rules, process, and monitoring that keep master data clean over time, so a one-time cleanse does not degrade back to a mess.
Why is a one-time cleanse not enough?
Clean data drifts. Without controls, duplicates and gaps creep back as new records are created, and you end up cleaning it all again before the next change.
What does good governance include?
Clear ownership per domain, validation rules at the point of entry, a process for creating and retiring records, and monitoring so quality is measured rather than assumed.
When should we set up governance?
During the migration. You are touching every record anyway, so it is the rare moment you can enforce ownership and controls across the board.
Does governance slow the business down?
Done well it speeds it up, because everyone works from trusted data and stops reconciling conflicting records. The controls sit at entry, not in the way of work.
How does governance help AI?
AI fails for the same reason BI fails: a broken data foundation. Governance keeps the S/4HANA core clean and trustworthy, which is the prerequisite for reliable AI.
