Will batch sizes impact planning, costing, or stock accuracy?
Yes, and here’s how:
Planning: MRP and capacity planning will respect lot size rules. It can plan in multiples of the defined batch size.
Costing: Per-batch costing (if enabled) uses production lot sizes to break down fixed and variable costs.
Inventory Accuracy: Prevents issuing random quantities, which may cause discrepancies in stock vs. production output.
