Manufacturing has no behaviour switches of its own to speak of; what shapes it is accounting structure and master data:
- The module and its neighbours — Manufacturing requires Products and Inventory (§10.2), switched on together.
- The two flagged accounts — somewhere in your chart (Chapter 7), one account is flagged as the work-in-progress account and one as the manufacturing variance account. Posting an issue without the first, or closing without the second, is refused with the missing account named — a deliberate block, not an error to work around. Which accounts carry the flags is a setup decision, made with the Implementation Manual open.
- Standard costs (§6.8) — the build-up that prices a release comes from component costs; stale standards make stale work orders.
- BOMs, kept truthful (§10.6) — the single most consequential "setting" in the module is a recipe that matches the factory floor.
- The work-order number sequence — set with the other sequences in System Setup (Chapter 16).
- The lifecycle permissions — release, complete and close (§10.8).
