# SAP Error: Define QM Procurement Key (How to Fix It) > Source: https://netray.co/erp-help/sap-define-qm-procurement-key-error-fix > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Help ## Short answer This error means the material master (or a vendor or plant setting) points at a QM procurement key that has not been defined in customizing for that client. Define the key in the IMG under Quality Management in Procurement, activate QM in procurement for the plant, then make sure the QM view of the material uses a valid key and control key. ## Kind error ## System sap ## Erp SAP S/4HANA and ECC ## Module Quality Management in Procurement / Material Master ## Query sap error define qm procurement key ## Alternate Queries - sap qm procurement key not defined - qm proc active material master error - sap qm procurement key plant activation ## Applies To SAP ECC 6.0 and SAP S/4HANA on-premise with QM in Procurement ## Steps ### Fix the missing QM procurement key **Items:** - Note the plant, material and the exact message from the status bar. Use the long text to see which field it names. - In SPRO go to Quality Management > QM in Logistics > QM in Procurement and open 'Maintain QM Procurement Key'. Check whether the key exists for your client. - If it does not, create it with a key, a description and the settings for whether a QM system or quality assurance agreement is required. - Activate QM in procurement for the plant in the same IMG area (activate QM in procurement). - Open the material in MM02, QM view, and tick 'QM proc. active' for the plant. Then set a valid QM control key. - If the vendor is involved, check the QM data on the vendor and the source list or info record (QI01 for quality info record) for any requirement. - Retry the goods receipt or purchase order. Transport the customizing to production and not just the material change. ## Sections ### What the QM procurement key controls **Body:** The QM procurement key defines the quality requirements that apply when a material is procured: whether the vendor needs a QM system, whether a quality assurance agreement is required, and whether the material is blocked for procurement until those requirements are met. In the material master QM view, 'QM proc. active' activates quality management in procurement for the material and plant. The QM control key (distinct from the procurement key) defines which procurement-related actions apply, such as an inspection at goods receipt or a certificate requirement. If the plant is not activated for QM in procurement, or the key does not exist in the client, material and plant data cannot be saved or used in PO or goods receipt. ### Why the key is missing **Body:** The commonest causes are a transport that included the material master change but not the customizing, a new client or system copy where the IMG settings were not carried across, and a plant created after the QM configuration was done. Another cause is a key that was deleted or never defined for a particular key value, for example copied from the legacy system through a migration load. Check that all key values in the migrated data exist in customizing before loading. Check that the master data is in sync with the quality system. A recently activated plant may still lack a QM control key for existing materials. **Code:** - SPRO > Quality Management > QM in Logistics > QM in Procurement > Maintain QM Procurement Key - SPRO > Quality Management > QM in Logistics > QM in Procurement > Activate QM in Procurement - MM02 Material master > QM view > QM proc. active, QM control key - QI01 Create quality info record ### Verifying the fix **Body:** After defining the key, display the material in MM03 for the plant and check the QM view. Create a test PO (ME21N) and post a goods receipt (MIGO). If the control key triggers an inspection, an inspection lot should appear. If the system still complains, check client-specific settings: customizing can be client dependent. A test in client 100 does not help if your issue is in client 200. For a mass of materials, use a mass change (MM17 or a LSMW/migration cockpit run) to set the QM fields, and verify with a table query on the QM fields instead of opening each material. ## Pitfalls - Fixing the material master without defining the key in customizing. - Activating QM in procurement for a plant but not setting a control key on materials. - Testing in the wrong client. - Forgetting that transports of master data and customizing arrive separately. - Loading migrated materials with key values that do not exist in the target. ## Ai Angle This is a classic 'which of the 4,000 materials is wrong' problem. A grounded assistant can query the QM view data against the defined keys and list every material and plant using an undefined key, then group by cause. Netray can run that against your SAP database on your own infrastructure, read-only, so the finding comes with the query it used and you decide the correction. ## Faq ### What is the QM procurement key in SAP? **Answer:** It is a customizing key that defines quality requirements for procuring a material, for example whether a vendor needs a QM system or a quality assurance agreement. It is referenced from the QM view of the material master. ### Where do I activate QM in procurement for a plant? **Answer:** In SPRO under Quality Management > QM in Logistics > QM in Procurement there are nodes to define the key and to activate QM in procurement at plant level. The exact labels vary slightly by release. ### What is the difference between the QM procurement key and the QM control key? **Answer:** The procurement key sets the quality requirements for the vendor and procurement. The QM control key decides which actions occur, such as inspection at goods receipt or certificate requirement. ### Why does the error appear only in production? **Answer:** Usually the customizing transport did not reach production or was imported to a different client. Compare the entries in both systems and re-transport. ## Search terms sap error define qm procurement key, qm procurement key sap, qm proc active sap, sap qm control key material master, activate qm in procurement plant, sap quality info record qi01, sap qm in procurement configuration --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
