3. Definitions:
Totals: A setting that when enabled, displays column sum in the bottom row of the
Single Level BOM screen
Formula: a mathematical function created by the Formula Builder in a single cell.
May be applied to all rows, even sub-levels when defined as “Rollup”
Rollup: A feature of a formula. When a formula is defined as a “Rollup” OpenBOM
will look down all sub-levels, SUM that property (often Cost) and return the SUM
up one level. Multi Level BOMs only.

Rollup mechanics!

7. Troubleshooting
#ERR is an indication that you have a problem with your formula. Hover over the cell to see more
information about what is wrong. Should be a red triangle.
Formulas support one set of parens ( ).
Rollups must have only two values: Ex. Cost * Quantity
Up to two property rollups or Totals per BOM (ex. Mass and Cost)
