A row on the Issues page opens the dialog on its Issues tab. AF Elements have no graph; open a child attribute or analysis to trace it.
Dialog actions
| Action | Where | Objects | Role |
|---|---|---|---|
| Back (or Esc) | Header | All, after moving through related objects | Any |
| Close | Header | All | Any |
| Check health | Header | PI Points, AF Attributes, AF Analyses, PI Interfaces, PI Adapters | Operator |

Dependency graph controls
| Control | Effect |
|---|---|
| Detail / Assets | PI Vision displays: the datasource chain, or attributes and analyses grouped by AF Element. Template-based displays open in Assets |
| Types | Hide object types |
| Health | Hide Good, Warning, Error or No status nodes |
| Labels | Edge labels: Auto, All, None |
| Reset | Clears the filters. Dashed edges keep paths through hidden nodes |
| Find a node or type | Search; step with the previous and next buttons |
| Hover a node | Highlights its direct connections |
| Pin a node | Upstream, Downstream or Both; Direct or Full path; Isolate; Clear focus |
| Node buttons | Expand or collapse upstream and downstream; AF Elements in asset context expand attributes and analyses; AF Attributes show a Limits popover |
| Export SVG | Saves the current graph |
| Open fullscreen | More room |
| Minimap | Shown from 10 nodes |
| Limit | Value |
|---|---|
| Stack | 10 or more nodes with the same relationship are grouped into an expandable stack |
| Expansion | Stops at 250 nodes |
| External system graph | 60 nodes, unhealthy and missing PI Points first; the Connections tab lists all |
| Limited view | The graph reached its limit; inspect Usage, Datasources or Connections for the full set |
Node colours show the type: PI Point, AF Attribute, AF Element, AF Analysis, PI Vision Display, PI Vision Calculation, External System, inferred External Source. An inbound external-system arrow means the system supplies the PI Point; outbound means the PI Point supplies the system. When a curated inbound source exists, the inferred InstrumentTag source is hidden.
Issues page filters
| Filter | Options |
|---|---|
| Search | Object name, path or issue message |
| Severity | All severities, Errors, Warnings, Info |
| State | Active issues, Suppressed issues, All issues |
| Category | All categories, PI Points, PI Interfaces, PI Adapters, AF Attributes, AF Analyses, PI Vision, External Systems |
| Issue type | All issue types, then the types currently open |
| AF template | Issues of objects based on a template |
| First discovered | Any time, Last 24h, 1-7 days, 8-30 days, 1-3 months, Over 3 months, Custom range |
| Column | Content |
|---|---|
| Object | Name and path |
| Issue | Issue type |
| Message | The finding |
| Days open | Age since first discovered, or New, with Last seen |
| Action | Suppress or Restore (Operator); acknowledge for host issues |
Severity and category show as badges. Selecting rows offers View downstream impact of selected.
Downstream impact
| Item | Value |
|---|---|
| Entry points | Show affected analyses (detail More actions, PI Point Usage, AF Attribute Datasources); View downstream impact of selected (Issues page); Recalculate analyses (PI Points page, PI Interfaces, PI Adapters, AF Elements) |
| Dialog title | Affected analyses, or Analysis Recalculation when you may prepare a run |
| Results | Direct and indirect consumers, each once; healthy analyses included; Path explains the relationship |
| Coverage | Limited coverage means the list may be incomplete; zero results with limited coverage is not proof of no impact |
| Selection | Up to 100 analyses for Continue; Select all only with complete coverage |
| Export | Export / Export selected (Operator; not in Evaluation) |
