Inventory Management

Interview questions covered

• You are designing batch management strategy for a multi-plant, multi-vendor pharmaceutical rollout where valuation is at plant level. What architectural decisions must be addressed regarding batch level and vendor-specific batch tracking?
• During cutover, stock migration for a plant integrated with PP (with active production orders) shows discrepancies between migrated stock quantities and legacy inventory once the first post-go-live goods movements occur. As the lead consultant, what would you investigate?
• What are negative stocks in Inventory Management, and under what conditions can they be allowed in SAP?
• When planning stock migration into S/4HANA for a client also implementing embedded/decentralized EWM, what architectural decisions must be made regarding the sequence and scope of stock migration objects?
• How does the shelf-life expiration date check integrate with FI-GL postings when a batch-managed material moves from unrestricted-use stock to blocked stock upon expiration, and which transaction keys are involved in maintaining valuation continuity during this transfer?
• At month-end, inventory closing activities reveal that several goods movements posted after the period was supposed to be closed for MM, resulting in inconsistent valuation figures. How would you investigate the root cause and prevent recurrence?
• In a scenario where reservations for production orders are not being consumed correctly and stock appears reserved but unavailable for other orders, what root causes would you investigate from an inventory management perspective?
• A warehouse team moves serialized stock between storage locations using movement type 311, quantities update correctly in MMBE, but at month-end the Material Ledger quantity ledger for that material appears out of sync. As a consultant relatively new to Material Ledger, what basic checks would you perform to troubleshoot this?
• What is stock determination in SAP Inventory Management and why is it used during period-end inventory close activities?
• During cutover weekend, stock migration to S/4HANA Public Cloud is complete, but subsequent SD sales order availability checks show incorrect stock quantities at several plants. What troubleshooting steps would you take?
• What is stock-in-transit in SAP Inventory Management, and which movement types typically represent goods that have left an issuing plant or storage location but have not yet been received at the destination?
• A quality inspector releases stock from quality inspection to unrestricted use, but finance reports that no accounting entry was generated for this transfer. Why might this be expected behavior, and what would you check to confirm it?
• How does moving material from unrestricted-use stock to quality inspection stock (movement type 321/322) interact with Material Ledger, and does this transfer create a financial posting?
• What is a reservation in SAP Inventory Management, and does it have any direct impact on the general ledger?
