W090: Update BOM

Replaces the full composition for an output SKU's BOM. Triggered from BOM Detail. The replacement is atomic; partial intermediate states are never visible.

Steps​

  1. Load the BOM. Call BOM.getBomById.

  2. Validate input rows. For each row, confirm the referenced material or input SKU exists and respects the XOR invariant.

  3. Replace the composition. Call BOM.replaceBomItems. Atomic delete-then-insert at the L2 layer.

Returns​

The updated BOM with its items.

Business rules​

  • Replacement is atomic. Readers never see a partial composition during the update.
  • No retroactive cost cascade. Existing WOs keep their frozen recipe snapshot; only WOs created after the edit pick up the new recipe and roll-up costs.

Errors​

  • NotFoundError. The BOM or a referenced input was not found.
  • ValidationError. An input row violates the XOR invariant.
