Short answer
Turn on whole-unit rounding when a material can only be ordered as a complete box, tube, bundle, carton, or packaged accessory. Leave it off when your supplier accepts the calculated fractional quantity.
When To Turn This On
Use whole-unit rounding when the calculated quantity can be fractional but your supplier only sells the item in whole packages.
- Good examples include boxes of screws, tubes of sealant, bundles of cleats, cartons of accessories, and packaged pipe boots.
- For materials you can order by custom LF or SF, leave rounding off unless your supplier requires a package quantity.
- When rounding is off, the formula preview shows the calculated quantity without an After rounding step.
- When rounding is on, the quantity rounds up after Multiply, Divide, and Add Extra are applied.
Example
If a screw line calculates 3.2 boxes and whole-unit rounding is on, the order quantity becomes 4 boxes. If rounding is off, you will see 3.2 boxes and can decide how you want to handle it.
Where To Change It
Open the Material Order tab, edit the Order Template, expand a material line, and use the Round up to whole order unit checkbox. Check the formula preview so you can see the quantity before and after rounding.
