Where used

Every place an item appears, across every product in your company. Use this to answer "what breaks if I change this?" before you change it.

Opening it

Three ways in:

• Select the Shared label on any row.
• Select the N× places label in the Summarized view.
• Open any row's detail panel and go to Where used.

What it shows

Each entry is one position the item occupies, given as a full path from the top-level product down to the item.

For each position you see:

• Qty, what that line calls for.
• Ext, how many that position needs for one finished product.

The footer totals demand across every product.

Using it before a change

Before editing, moving or removing anything marked Shared, open this tab.

It answers three questions at once:

1. Who else uses this? Every product, by name.
2. How much do they need? Per position, and in total.
3. How deep does it sit? The path shows whether it is a top-level module or buried several levels down in someone else's assembly.

The third one matters at release time. Everything on the path above the item has to be released again when it changes. See How releases work.

An item used nowhere

If nothing uses it, the tab says so.

• That is expected for a top-level product.
• On an assembly it is worth a second look, because it may be work nobody picked up.
