Every module gets its own triage room — flashcards that tell you what's going on in plain words, the fix step by step, exactly where to click in Fusion, and the diagnostic SQL on a copy button. Two rooms are open; the next one gets built where the votes point.
The cost processor triage room: decode any error (negative inventory, missing layer costs, period deadlocks, ORA-classics), transactions that won't cost by type, stuck processes, valuation reports that won't reconcile, and the setup pre-flight.
🧾The AP invoice hold diagnoser: every common validation hold — quantity received, price, no rate, tax variance and friends — with ordered checks, root causes, fix paths and the senior tips the docs skip.
🗳️Receivables? GL & close? Receipt accounting? Order Management? The next triage room gets built where the votes point — cast yours on the Wishlist.
One habit worth stealing: come here FIRST, before the SR. Most of what stops a costing run or holds an invoice is self-service — and every card cites the Oracle note for the deep dive when it isn't.
