To create or import a BOM click the "New BOM Tab" menu.
You can open as many tabs as you want at once.
The first thing to do is create a "root"
item - this item doesn't need to be in the inventory
database. All other items need to be added as
children of this item in order for the prices to roll up
to a single item.
Right click anywhere in the whitespace
to open the context menu, select Add/Insert blank item
here (or you could insert an existing item, create a new
item or insert a saved BOM).
Give it a description and set the unit
quantity. After you've added items, changing the
unit quantity recalculates the costs all the way down
the tree, as we'll see later. FYI you can create
multiple root items if you want to store multiple
assemblies in the same file. But they won't roll
up into a single cost.
You can now add items under this node. From the context
menu, selecting "insert existing item here" opens a
window with the entire inventory to select from.
You can filter items by typing in the Filter box.
You can filter on a selection of fields. Here we
see all items with the word "crystal" in any of the text
fields. Select an item and click OK or
double-click on an item.
As you add items you can see the stock usages, unit
costs and cost rollups at each level.
You can adjust the unit quantities of any item.
Changing one at any level recalculates the entire tree.
BOMcalc will use the correct prices based on the number
of items required.
Here we have changed the unit quantity of the root item
to 5. Notice all of the stock quantites and prices
Notice the checkboxes across the top of the tree view.
Ticking these boxes provides different views of your BOM
costs with in stock, on order and to order considered.
With none of the boxes ticked, these metrics are not
considered and stock shortages, etc. are calculated as
if you had no stock, etc. This gives you a picture
of how many of each item and how much it would cost if
you had no stock at all.
This time we have also ticked "include on order qty" to
see how it affects things. Notice that now the
total cost is blank ($0) now because there's enough
stock to cover the production.
