The coding options for costing and reporting <labor in work centers are all based in some form or fashion on the number of <units produced. Set-up time does not relate to the lot/batch size, it's <constant. Allow me to respond: The Set-Up time in the routing is a fixed amount of time regardless of the shop order quantity. It is a fixed amount of time to 'set-up' the operation everytime the item is made. For Capacity reports, it is always a fixed amount of time. The 'Problem' usually occurs when you you try to apply the cost of setup to the unit cost of the item being produced. BPCS takes the total setup dollars and divides it by the 'usual' or 'standard' or average' quantity produced. This quantity is known as the Lot Size and is either the one in the Item Master or in the Item/Facility if running by facility. When a shop order is closed/costed, the setup time is divided by the quantity produced ( not by the lot size). Why are you changing the standard Lot Size ?
