The **aBOM** tab in Build Readiness shows the installation status of every part in your as-built BOMs, with cost rollups and issue counts per component. Each row is one required part within one top-level serialized assembly. To open the dashboard, go to **Analytics > Build Readiness > aBOM**.

## Filters

**Part Number**: narrows all KPIs, charts, and table rows to a single top-level assembly part number. Selecting a part number resets the **Rev** and **Serial** filters.

**Rev**: further narrows to a single revision of the selected assembly. Resets the **Serial** filter.

**Serial**: further narrows to a single serialized instance of the selected assembly.

**Hide root nodes**: when enabled, hides the row where the part is the top-level assembly itself, so the table shows only child components.

## Sub-tabs

The aBOM tab contains two sub-tabs sharing the same filters:

- **aBOM**: the full installation detail table with cost and linkage columns.
- **Issues**: filtered to only rows that have at least one issue, with the same column set.

## KPI cards

| Card          | What it shows                                                                 |
| --------------| --------------------------------------------------------------------------- |
| Total Cost   | Sum of `TOTAL_COST` across all rows in the current filter.                  |
| Total Parts   | Number of distinct top-level assembly instances in the current filter.       |
| Fully Installed| Number of assembly instances where `IS_FULLY_INSTALLED` is true, and the percentage of the total. |
| Open Issues   | Sum of `OPEN_ISSUE_COUNT` across all rows.                                   |

The **Issues** sub-tab shows two additional cards: **Open Issues** and **Total Issues** for the filtered set.

## Export

The **aBOM** sub-tab and the **Issues** sub-tab each have their own export. Click **Export** in the table toolbar to download the current view as a CSV. Both exports respect all active filters; the Issues export additionally filters to rows with at least one issue.
