What are MM02 and MM03 in SAP?

You may need to change certain options in the Material Master because of organizational changes or evolving business processes. Transaction MM01 cannot be used for these updates because MM01 only creates views that are not yet maintained for a material. To edit existing data you use MM02, and to view data without the ability to change it you use MM03.

In SAP, transactions that end with 01 are used for créez. records, transactions ending with 02 are used for editing or changing them, and transactions ending in 03 are used for visualisation records in read-only mode.

FAQ

MM01 creates a new Material Master record or new views. MM02 edits existing Material Master data. MM03 displays the record in read-only mode with greyed-out fields. This 01/02/03 pattern is a common convention across many SAP master-data transactions.

MM02 does not have a built-in undo. Reversing an MM02 change means manually editing the field back to its previous value. SAP records every change in the document history, so administrators can refer to the audit log to identify the original value.

MM03 is a display-only transaction. Fields are greyed out to prevent accidental edits and enforce read-only access for users who need to view Material Master data without authorization to change it. Use MM02 instead when editing is required.

AI identifies duplicate Material Master records, predicts missing fields, recommends classification codes, and detects data anomalies. AI copilots also suggest enrichment values from supplier catalogs, reducing manual effort and improving downstream procurement, planning, and reporting accuracy.

Yes. AI models compare proposed MM02 edits against historical patterns, related materials, and master-data rules. If a change deviates significantly, the AI flags the risk before save, preventing pricing errors, incorrect units of measure, or broken downstream MRP planning.
