The Right Way to Handle ERP Master Data

Master data is the foundation that everything else in your ERP sits on. Customers, suppliers, items, bills of material, work centers, chart of accounts. When this data is wrong, corrupted, or inconsistently maintained, every operational and financial report built on top of it is compromised.

The common problems

Duplicate records are the most prevalent issue. The same customer entered twice under slightly different names. The same part with different item numbers in different business units. Duplicates do not just create reporting confusion - they create operational problems when orders split across records or inventory does not reconcile.

Inconsistent categorization means your reporting categories are meaningless. If half your customers are categorized by industry and the other half by region and some have no category at all, you cannot analyze your customer base by either dimension reliably.

Missing required fields are often masked by the ERP allowing records to save without them. A supplier with no payment terms. An item with no cost. These gaps cause downstream failures that surface in unexpected places.

The governance model

Every data type needs an owner. Who is responsible for the accuracy of your customer master? Who approves changes to item records? Who is authorized to add new suppliers?

Data governance does not need to be bureaucratic. It needs to be clear. One person per data domain, a defined process for changes, and a periodic review cycle.

The cleanup process

Do not try to clean everything at once. Prioritize by impact: which master data problems are affecting the decisions you make most often? Start there, establish governance before you move to the next category, and work progressively.

If you are planning an ERP implementation or migration, master data cleanup should be your first workstream, not your last. Reach out if you want help structuring the process.
