Setup Time as handled at the Operations tab items of the BOM. Define the setup Operation in Operations. Add the Operation to the Related BOM. Enter the Operation Time in minutes. Chek it as Fixed Time.
Please see below.
In Operations, I can configure two different operations - one for setup and one for the actual process.
This is very suitable for baking - as we have to turn on the oven once, and each cake does not take additional setup time. However, in job work scenarios like moulding, printing - the setup time is relevant for each job. You first setup the new design / artwork, and then the process happens.
If we create two separate operations - setup and process, we need to create two separate job cards, which is counter-intuitive. In general, this is combined in one operation.
ERPNext v15 does not have a built-in Setup Time field in BOM Operations. You can create a custom field in BOM Operation for setup time and use a server script to include it in production time calculations. Alternatively, calculate it manually by adding the workstation setup time to each operation.
