Material Master Data in SAP: Best Practices for Manufacturers

If your business runs on SAP, your material master is the foundation everything else is built on. Procurement runs off it. Production planning depends on it. Inventory management, costing, quality inspection, goods movement — all of it traces back to the material master record.

Which makes it all the more surprising how many manufacturers are running SAP with material master data that nobody fully trusts.

Duplicate records nobody wants to delete in case something breaks. Fields populated inconsistently across plants because each site has always done it differently. Change requests handled by email because there’s no governed process in the system. Data that was migrated from a legacy system years ago and never properly cleaned up.

This isn’t unusual. It’s the norm. And it creates real operational problems — wrong materials ordered, production plans built on inaccurate stock data, compliance audits that become a scramble.

This article covers what good material master data management looks like in SAP, the most common places it goes wrong, and the best practices that actually fix it.

What is material master data in SAP?

In SAP, a material master record is the central source of information about a material. Every raw material, component, semi-finished good and finished product your business uses has one. It contains everything SAP needs to process that material across procurement, production, inventory, sales, costing and quality — all organised into views.

Those views are important to understand because they’re at the heart of how SAP structures material data. Each view is owned by a different function:

The Basic Data views contain general information like material description, base unit of measure, material group and weight. This is the foundation that all other views build on.

The MRP views contain planning data — procurement type, lot sizes, safety stock, planned delivery times. Production planning runs off this.

The Purchasing view contains supplier-relevant data including purchasing group, order unit and goods receipt processing time.

The Plant Data and Storage views contain warehouse-specific information about how the material is stored and handled at each location.

The Accounting and Costing views contain valuation data — price control, standard cost and moving average price. Finance runs off this.

The Quality Management view contains inspection data relevant to goods receipt and production quality checks.

Each view is maintained by a different team. And that’s precisely where most material master data problems begin.

Where it goes wrong in SAP environments

Nobody owns the full record

Because different views are maintained by different departments, nobody tends to own the material master record as a whole. Procurement owns the purchasing view. Planning owns MRP. Finance owns costing. When something goes wrong — a field is wrong, a value is missing — everyone assumes it’s someone else’s problem.

The result is that records drift. Fields get updated in isolation. Changes made in one view aren’t communicated to the teams who depend on another. The material master becomes a patchwork of data maintained by multiple hands with no single point of accountability.

Creation happens too fast and too loosely

In most SAP environments, anyone with the right transaction code can create a new material. MM01 is not a governed process by default. Users create materials at pace, often under pressure to get a new product live or a new procurement process started, and the quality of what goes in reflects that pressure.

Descriptions that don’t follow naming conventions. Units of measure that don’t match the purchasing standard. Classification codes that are wrong or missing entirely. Once the record is in SAP it gets used, gets transactions posted against it, and becomes very hard to clean up without operational disruption.

Duplicate records accumulate silently

When a user can’t find a material, they create a new one. This is the root cause of most duplicate material records in SAP. The original exists under a description the user didn’t search for, or in a plant they didn’t check, and rather than investigate they just create.

Duplicates are operationally expensive. Stock gets split across multiple records. Spend against the same material is invisible because it’s fragmented. Procurement loses leverage because purchasing history is diluted.

Change management is informal

Even in well-run SAP environments, material master changes are often managed outside the system. Someone emails a request. Someone else makes the change directly in MM02. There’s no workflow, no approval, no audit trail beyond the standard SAP change document — which records what changed but not why, and doesn’t require approval before a change takes effect.

This matters more than most manufacturers realise until they’re in a compliance audit and can’t explain why a critical field was changed three weeks before a quality incident.

Best practices for material master data governance in SAP

1. Standardise before you govern

Governance processes can only work if the data standards underneath them are clear. Before implementing any workflow or approval process, define the rules your material master data has to follow.

That means: naming conventions for material descriptions (what order do attributes appear in? what abbreviations are permitted?), approved units of measure for each material type, mandatory fields for each view and material type, classification structure and required characteristics.

Without documented standards, even a well-built governance process produces inconsistent output because different users are making different decisions within it.

2. Govern creation with a structured request workflow

New material creation should never start in MM01. It should start with a governed request that captures the required data for every relevant view, routes it to the appropriate owners for input and approval, validates it against your data standards before it reaches SAP, and only creates the record once all required fields are complete and approved.

This is where dedicated MDM software earns its place. SAP MDG (Master Data Governance) provides native functionality for this, but it has limitations — the interface is not intuitive for business users, configuration requires significant technical resource, and the standard object coverage is narrower than many manufacturers need. Purpose-built tools like Maextro provide the same governed creation workflow with a significantly lower implementation burden and a user experience that business teams actually adopt.

3. Enforce duplicate detection before creation

Duplicate checking should happen at the point of request, before anything reaches SAP. A user submitting a new material request should be shown potential matches based on description, material group, and key attributes — and should have to confirm that none of those matches is what they need before the request proceeds.

This doesn’t eliminate duplicates entirely, but it dramatically reduces the volume of avoidable ones. The ones that get through tend to be genuine edge cases rather than the result of users not checking.

4. Implement change request management

Every change to a material master record should go through a formal process. A user identifies that a field needs changing. They submit a change request through a governed workflow. The request is routed to the appropriate approver for that view and that plant. The approver reviews and approves. The change is made in SAP automatically, with a full audit trail linking the SAP change document to the original request and its business justification.

This sounds like overhead. In practice, once it’s running, it takes less time than the current email-based alternative — and it produces a governance record that is worth its weight in a compliance audit.

5. Use mass processing carefully and with validation

Most manufacturers need to make bulk changes to material master data at some point — a unit of measure standardisation project, a plant extension rollout, a re-classification exercise. SAP’s native mass processing tools are powerful but unforgiving. A bulk change without proper validation can propagate errors at scale faster than any manual process.

Mass processing should always go through the same validation rules as individual creation and change — ideally through a tool that allows bulk upload via Excel with field-level validation before anything touches SAP. Maextro’s bulk processing capability is built for exactly this: upload a spreadsheet, validate against your rules, review exceptions, approve and post. The same governance, applied at volume.

6. Extend governance to connected objects

Material master data doesn’t exist in isolation. A material record is connected to BOMs that reference it as a component, to routings that reference it as the output of a production step, to purchasing info records that link it to a supplier, to classification objects that place it in your product hierarchy.

Best practice isn’t just governing the material master itself. It’s governing the network of objects around it. When a material changes, what else needs to change with it? Who needs to know? A mature MDM approach in SAP builds workflows that consider these dependencies and route change notifications to the right people automatically.

7. Conduct regular data quality reviews

Governance prevents new problems from entering. It doesn’t fix the ones already there. For most manufacturers, the material master has years of accumulated technical debt: outdated records, fields populated incorrectly, materials that were created for a project and never used again, descriptions that predate any naming convention.

A regular data quality review — at least annually, ideally quarterly — should check for records that haven’t been used in a defined period, fields that don’t comply with current standards, potential duplicates introduced despite creation governance, and views that are incomplete for materials that are actively used.

This is less dramatic than a one-off data cleanse project and far more effective. Problems caught early are easy to fix. Problems left for three years are not.

The role of MDM software in SAP material master governance

SAP provides the system of record. What it doesn’t provide out of the box is a user-friendly, business-governed process for creating and maintaining material master data at scale.

SAP MDG adds some of this governance natively, but it comes with trade-offs: a complex implementation, a technical interface that requires training, and limited flexibility for manufacturers who need to govern more than the standard object set.

The alternative is purpose-built MDM software that sits on top of your SAP landscape — governing what goes in, routing approvals, enforcing validation, and providing the audit trail that compliance requires. Maextro is built specifically for SAP environments, deploys in 2 to 5 weeks on SAP BTP, and covers 16 master data objects including material master, BOM, routings, vendor, customer and more. It’s used by manufacturers including Babcock, Upfield, Carlsberg and BAE Systems to bring the kind of governance to their SAP material master data that the system itself doesn’t provide by default.
