## Calls

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 99000810 "Calculate Planning Route Line"](../codeunit/99000810.md) (3 calls: `CalculateRoutingFromActual → CalculateRouteLine`, `CalculateRoutingFromActual → SetResiliencyOn`, `OnGetResiliencyErrorOnRouting → GetResiliencyError`)
- [Codeunit 5402 "Unit of Measure Management"](../codeunit/5402.md) (1 call: `Calculate → QtyRndPrecision`)
- [Codeunit 99000755 "Shop Calendar Management"](../codeunit/99000755.md) (1 call: `CalculateRoutingFromActual → GetMaxDate`)

## Called by

- [Table 99000830 "Planning Routing Line"](../table/99000830.md) (8 calls: `CalcStartingEndingDates → CalcSequenceFromActual`, `CalcStartingEndingDates → CalculateRoutingFromActual`, `CalculateRoutingBack → CalcSequenceFromActual`, …)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC27

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: "PlanningRoutingManagement")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
