## Triggers

OnRun, Timer::Elapsed, Timer::ExceptionOccurred

## Called by

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 130400 "CAL Test Runner"](../codeunit/130400.md) (2 calls: `RunTests → Start`, `RunTests → Stop`)
- [Codeunit 130402 "CAL Command Line Test Runner"](../codeunit/130402.md) (2 calls: `OnRun → Start`, `OnRun → Stop`)
- [Page 9990 "Code Coverage"](../page/9990.md) (2 calls: `OnAfterGetRecord → FunctionCoverage`, `OnAfterGetRecord → ObjectCoverage`)
- [XMLport 9991 "Code Coverage Detailed"](../xmlport/9991.md) (2 calls: `OnPostXmlPort → Import`, `OnPreXmlPort → Clear`)
- [Page 9991 "Code Coverage Setup"](../page/9991.md) (1 call: `OnOpenPage → StartAutomaticBackup`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: none

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Code Coverage Mgt.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
