Questions about How to use Batch Size in Routing

ERP Next Shows that when you are creating a routing, a batch size (the number of units processed in this Operation) is assigned to each item in the BOM operations table.

Can anyone give examples of how they use this?

  • What happens if an line in the BOM operations table is for batch size of 10 but you are only making 2 products right now?
  • What happens when different lines in the BOM operations table for a routing has different batch sizes?

Does anyone have a suggestion about this topic or a part of documentation I can refer to?
