Browse the hierarchy¶
Navigate the five-level asset tree on the mobile app — search, expand, filter, and jump to a task point without having to scan anything.
Required role
Any mobile-enabled role.
Overview¶
NFC and barcode scanning are the fast paths to a specific task point. But sometimes you can't scan:
- The tag is damaged.
- You're nowhere near the asset.
- You're looking for something you haven't been to before.
The Hierarchy browser is the alternative. It's a scroll-and-tap view of the whole asset tree — Site → Line → Section → Asset → Task Point — so you can drill to any task point from the menu.
Prerequisites¶
- App is paired and signed in.
- Initial sync has completed (the hierarchy is cached locally).
Open the hierarchy¶
Menu → Hierarchy, or tap the hierarchy icon in the bottom navigation (if your device layout shows it).
You see a tree rooted at Production Sites. By default, only the top level is expanded.
Expand / collapse¶
- Tap the chevron next to any node to expand.
- Tap again to collapse.
- Long-press a node for Expand all descendants or Collapse all descendants.
The expand state persists while you stay on the hierarchy screen. Leaving and coming back resets to the default collapsed view.
Search¶
A search bar at the top of the hierarchy screen:
- Tap the bar.
- Type part of the name of any node at any level — site, line, section, asset, task point.
- Matching nodes appear as a flat list with their breadcrumb.
- Tap a result to open.
Search is case-insensitive and matches anywhere in the name (not just prefix).
Search beats browsing
If you know the name, search is faster than drilling. 3-letter search queries usually land within a second.
Open a node¶
Tap any node:
- Production Site / Line / Section / Asset → detail page. Shows basic metadata and child nodes. You can't execute work at these levels — keep drilling.
- Task Point → detail page with the task(s) attached. Tap a task to start.
Filters¶
The filter icon in the top-right:
- Only nodes with open tasks — hides anything without scheduled or assigned work.
- Only nodes assigned to me — narrows to what's in your queue.
- Specific task type — Electrical / Lubrication / Mechanical / Production / Repair request.
- Specific production site — only assets under that site.
Filters combine. Clear them via Reset filters.
Favourites (if enabled on your installation)¶
Some installations allow you to star specific nodes you visit often:
- Open the node.
- Tap the star icon.
Starred nodes appear in a Favourites tab at the top of the hierarchy. Useful for the five or six task points you work on daily.
Offline behaviour¶
The hierarchy is cached fully. Everything on this page works offline:
- Expand / collapse.
- Search.
- Filters.
- Open any node.
Changes you or someone else makes on the web portal propagate to your cache on the next sync cycle (every ~15 min).
What the breadcrumb shows¶
Every node's detail page has a breadcrumb trail at the top:
Tap any segment to jump up the tree. Useful if you want to go from one task point to a sibling on the same asset without backtracking.
Things to watch for¶
Learn the names that matter
After a week you'll know the names of the 20 lines you work on. Search by those; skip the tree navigation entirely.
Stale cache looks like missing data
If a task point someone told you about doesn't appear in the tree, your cache may be behind. Pull-to-refresh on the Dashboard to force a sync.
Filters persist
The filter icon shows a dot when filters are active. If the hierarchy looks surprisingly sparse, check the filters first.
Common patterns¶
Jumping to a known task¶
- Menu → Hierarchy.
- Search for the asset name.
- Tap the result.
- Tap the task.
Total: ~5 seconds.
Exploring an unfamiliar line¶
- Menu → Hierarchy.
- Filter by the line's production site.
- Expand the line.
- Browse its sections and assets.
Verifying structure as a mapper¶
- Open the hierarchy to the level you just created.
- Confirm the breadcrumb and metadata.
- Use Creating hierarchy to add / correct (see Creating hierarchy).
Troubleshooting¶
| Problem | Fix |
|---|---|
| Tree is empty | Initial sync hasn't completed; wait, or force sync |
| Can't find an asset that should exist | Clear filters; check spelling; force sync |
| Search is slow | Large plant + old device; use filters to narrow before searching |
| Tapping a node does nothing | Rare UI freeze; kill the app and reopen |
| Can't open a task from a task point | Check you're the assigned technician — viewing vs executing is role-gated |
