Change the process with the batch size
Twenty candles take one pour. Three hundred take a pot twice the size, two people and a different jig. One bill of materials can hold both: the quantity you are making decides which process applies.
Define the ranges
Section titled “Define the ranges”- Open the bill of materials and go to Batches.
- Click Manage ranges and Add range.
- For each range, enter From, To (leave the last one and up) and the Batch size.
- Choose which range carries the Planned cost, then click Save ranges.
The rules: the first range starts at 1, each starts one above where the previous ended, the last is open-ended so every quantity is covered, exactly one carries the planned cost, and there are at most five. Saving with no ranges removes them. The steps stay on the specification, and it has one process for every quantity.
The range carrying the Planned cost is the one the planned cost is read from, and price lists derive from. A production order uses the range its own quantity falls in.
Give each range its steps
Section titled “Give each range its steps”Above the tabs, the Batch range strip switches the card between ranges. Each range has its own batch size and its own works. The material lines are shared by every range: a quantity is restated for the range, or overridden where it really differs.
To start a range from another’s works, use Copy works from, choose the range and click Copy. If the range already has works, confirm Replace, because the copy replaces them and their material overrides.
Figures on the card name the range they are stated for. A range with no works yet says its runs carry no labor, so they are costed without any.
Batch size and automatic production
Section titled “Batch size and automatic production”Under Whole batches, a shortfall is rounded up using the batch size that the ladder gives for that quantity. See Make shortfalls produce themselves.
