The challenge

What was standing in the way

Twelve SAP systems had grown up around twelve different ideas of what good master data looks like. Each plant maintained its own naming conventions, its own mandatory fields and its own spreadsheet of local exceptions. Records created in one region routinely failed validation in another, and nobody could say with confidence which version of a record was authoritative.

The data quality team spent most of its week correcting records after the fact rather than preventing bad ones from being created. Every correction was itself a manual SAP transaction, and every correction carried its own risk of introducing a new error.

  • Roughly one in six new master data records required rework after creation
  • No single definition of a complete record across the twelve systems
  • Corrections were applied directly in production with no approval trail
  • Month-end reporting was routinely delayed by data reconciliation
The solution

How Promenta approached it

Promenta was deployed natively inside the existing SAP landscape, so no data left the client systems and no middleware was introduced. A single governance model was defined once and then enforced at the point of creation in every connected system.

Validation runs before the record is committed rather than after. Requesters see the problem while they are still in the request, which is the only point at which fixing it is cheap.

  • One shared definition of a complete record, enforced across all twelve systems
  • Field-level validation at the point of request, not after posting
  • Role-based approval routing that follows the existing org structure
  • Automatic duplicate detection against every connected system
  • Full audit trail written for every create, change and approval
The results

What changed

Within one quarter the error rate on newly created master data fell by 94 percent, and the data quality team shifted from correction work to governance work. Month-end reconciliation stopped being a scheduling risk.

  • 94 percent reduction in master data errors reaching production
  • 6,400 manual correction hours removed from the annual workload
  • Month-end close brought forward by two working days
  • Zero audit findings on master data governance in the following cycle
We had tried to fix this with training and with policy documents. What actually worked was making it impossible to create a bad record in the first place.
