SAP Consultant / SAP Developer Interview Questions

A nightly batch job in an automotive OEM's SAP ECC system runs a custom ABAP report that selects from VBAK and VBAP for the previous month's orders. Runtime has crept from 8 minutes to 47 minutes over two years. No index changes were made. How do you diagnose and fix the performance regression?

Your team inherited a 15-year-old ABAP codebase at a global pharmaceutical company. It has 4,000+ custom programs, many using obsolete statements like MOVE-CORRESPONDING on deep structures and SELECT * on wide tables. You've been asked to lead a modernization roadmap before the S/4HANA migration. Where do you start and what's your 18-month plan?

A consumer goods company is debating between a greenfield S/4HANA implementation and a brownfield system conversion from their existing ECC 6.0 EHP8 system. The ECC system has 12 years of transactional data, 3,200 custom objects, and integrates with 14 external systems. As the lead architect, how do you frame the decision?

After a go-live on S/4HANA 2022, the finance team reports that the universal journal table ACDOCA is growing at 4 GB per day, far more than the 1 GB estimated during sizing. The system is an on-premise installation with limited storage expansion lead time. What do you investigate and what short-term mitigations exist?

A multinational manufacturing company runs legal entity consolidation across 23 subsidiaries in 8 currencies using SAP Group Reporting in S/4HANA.

An e-commerce company processes 50,000 sales orders per day via an API integration with their Shopify storefront. After a year of operation, they're seeing a 0.3% order failure rate at the billing document creation step. Each failed billing blocks a shipment and requires manual intervention. Design a root cause analysis and a permanent fix strategy.

Your team deployed a Node.js microservice to BTP Cloud Foundry that calls an S/4HANA OData API. In production, the service starts returning 401 errors after exactly 12 hours of uptime. Locally, it works fine. What's the most likely cause and how do you confirm and fix it?

A retail chain processes 200,000 IDocs per day for inventory movements between their 400 stores and the central SAP system. During a peak weekend sale, IDoc processing lagged 6 hours behind, causing stock levels shown in the e-commerce storefront to be stale. Design a permanent fix without a hardware upgrade.

A legacy HR system sends employee master data to SAP HCM via a flat file every night. The file sometimes contains records with invalid cost center assignments that don't exist in the SAP org structure. These cause the entire IDoc batch to fail, blocking all 500 employee updates until Monday morning support staff arrive. How do you redesign the error handling?

You're leading the data migration for a brownfield S/4HANA conversion at a steel manufacturer with 2.1 TB of application data, 18 million open items in FI, and 4 million material documents. The migration window is a 3-day weekend. How do you structure the migration approach and derisk the cutover?

You created a CDS view with association to a customer master and activated it successfully in development. After transporting to quality, a Fiori app using this view's OData service returns no data for certain customers. The same customers return data when querying the view directly in SE16N. What do you investigate?

A global ERP system on S/4HANA has a month-end close that involves 40 parallel background jobs. The close takes 14 hours and the business wants it under 8 hours.

During an S/4HANA system conversion, the test team discovers that a custom pricing user exit (MV45AFZB) that reads a custom pricing condition type is no longer triggering correctly in S/4HANA. The same code worked in ECC. The pricing exit was business-critical for a special discount applied to 40% of all orders. How do you diagnose and remediate?
