What problem does it solve? SAP MM postings like goods receipts, invoices, and stock transfers write directly to the general ledger, so a wrong action creates permanent financial documents. This Skill gives an AI agent the judgment to classify each SAP MM operation as read, reversible write, committing write, or destructive, and to know when to stop for human approval. ## Core Features & Use Cases - Operation Classification: Maps SAP MM transaction families (ME21N, MIGO, MIRO, movement types 101/102/261/321/551) to read/write/destructive risk classes with gating rules. - Edge-State Handling: Covers consignment, subcontracting, project/sales-order stock, split valuation, batch/serial management, and price control S vs V so quantity and value reasoning stays correct. - Recovery & Guardrails: Documents what can and cannot be undone (GR reversal, scrap, MR11 write-off, closed posting periods) and the guardrails for release strategies and vendor blocks. - Use Case: When asked to post a partial goods receipt against a PO in SAP, the agent reads the PO and period status first, recognizes the GR as a committing ledger event, and routes it for human approval instead of posting blindly. ## Quick Start Ask the agent how to safely post a goods receipt for a purchase order in SAP and whether it needs approval.
