Purchase Requisition

Lessons in this topic

• MM Purchase Requisition Part 1: The Purchase Requisition Lifecycle, Item Data and Account AssignmentThe purchase requisition is the internal request to procure. Learn how PRs are created (manually, by MRP, from sales orders or projects), the key item data, document types, item categories and account assignment categories, and the PR lifecycle from creation to conversion and closing.
• MM Purchase Requisition Part 2: Source Determination for PRs — Source Lists, Quotas and Info RecordsHow a supplier gets assigned to a requisition: sequence of quota arrangements, source lists (fixed sources), outline agreements and info records; manual versus automatic source assignment; regular supplier indicators; and what blocks automatic assignment.
• MM Purchase Requisition Part 3: MRP-Generated vs Manually Created RequisitionsUnderstand requisitions created by MRP versus users: how MRP calculates quantities and dates, firming and changes by MRP runs, when buyers should (not) change MRP requisitions, planning time fence, and how to handle manual requisitions for non-planned items.
• MM Purchase Requisition Part 4: PR Approval — Classic Release Procedure vs Flexible WorkflowApprove requisitions: classic release strategies with classes, characteristics, release groups/codes and item vs overall release, compared with S/4HANA flexible workflow for purchase requisitions — conditions, steps, agents, and how to choose and migrate.
• MM Purchase Requisition Part 5: Converting PRs to POs and Troubleshooting ExceptionsTurn requisitions into orders: manual conversion (ME21N with reference, ME57), automatic conversion (ME59N) prerequisites, Fiori apps for buyers, grouping of PRs into POs, and why conversion fails — no source, not released, blocked supplier, missing data, deletion flags.

Interview questions covered

• During hypercare of an Ariba integration project, sales order-driven procurement (third-party/drop-ship) records migrated from ECC are creating mismatched Ariba requisitions because SD-linked purchase requisition migration objects didn't carry over the sales order reference correctly. How do you troubleshoot this?
• Buyers across multiple purchasing groups report that certain fields on purchase requisitions are mandatory for one group but should be optional for another, yet the field selection is being applied globally. As the architect, how do you diagnose and resolve this?
• In a Central Procurement hub scenario connected to multiple S/4HANA Public Cloud execution systems, sales order-driven third-party purchase requisitions from an SD-integrated execution system are not appearing in the central procurement worklist. How do you troubleshoot this?
• As solution architect, how would you design purchase requisition document types to support both self-service (employee) requisitions and centralized strategic sourcing requisitions across a multi-country S/4HANA rollout, considering downstream FI-AP posting consistency?
• During an S/4HANA Public Cloud migration, sales order-driven third-party purchase requisitions migrated via Migration Cockpit are missing the SD sales order reference (VBAP/VBEP linkage), causing procurement teams to lose traceability between the PO and originating sales order. How would you troubleshoot and fix this using the available migration objects and APIs?
• During a P2P migration to S/4HANA, purchase requisitions created for SD-driven third-party sales orders are migrating successfully via Migration Cockpit, but after a subsequent release upgrade the sales order reference on some migrated requisitions is lost, breaking third-party billing. How would you troubleshoot this?
• What is the purpose of purchase requisition document types in SAP MM, and how do they influence downstream processing?
• Explain the purchase requisition lifecycle and how item and account assignment categories influence later postings.
• Many requisitions stay unsourced and buyers assign suppliers manually. How do you improve automatic source determination?
• A company with dozens of classic PR release strategies moves to S/4HANA. How do you redesign PR approval?
• How would you use and troubleshoot MB_CHECK_LINE_BADI in a real SAP project?
• A user receives SAP message M7 021. How would you diagnose the root cause and resolve it safely?
• How would you use and troubleshoot MB_DOCUMENT_BADI in a real SAP project?
• Planners complain that MRP creates too many requisitions with wrong dates, and buyers edit them weekly. How do you fix MRP-generated requisitions?
• Hundreds of requisitions are not converted automatically each night. How do you troubleshoot PR-to-PO conversion?
• After go-live, sales orders created for intercompany stock transfer are not triggering the expected Ariba purchase requisition flow in a hybrid SD-MM-Ariba landscape. What integration points would you check first?
