Part 1
Course reading
A consultant explains business processes before transaction codes. Start with the requirement, current process, roles, master data, documents, exceptions and controls. Then explain how standard SAP MM or EWM supports it and where a gap remains. Avoid promising custom development before evaluating standard behaviour.
Prepare an end-to-end example such as purchase requisition to invoice, inbound delivery to putaway, or outbound delivery to goods issue. Name the important organizational levels and integration points, but only discuss configuration you genuinely understand. Explain unit testing, integration testing, user acceptance testing, cutover and hypercare in plain language.
For support, use a reproducible incident: user, plant or warehouse, document number, expected result, actual result and screenshots or logs permitted by policy. Explain how you checked master data, stock status, document flow and authorizations without changing production data experimentally. Interviewers value a safe, structured approach more than a memorized list of transactions.
