## 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 5611 "Calculate Normal Depreciation"](../codeunit/5611.md) (1 call: `Calculate → Calculate`)
- [Codeunit 5612 "Calculate Custom 1 Depr."](../codeunit/5612.md) (1 call: `Calculate → Calculate`)
- [Codeunit 5616 "Depreciation Calculation"](../codeunit/5616.md) (1 call: `CheckDeprDaysInFiscalYear → DeprDays`)
- [Codeunit 5617 "FA Date Calculation"](../codeunit/5617.md) (1 call: `CheckDeprDaysInFiscalYear → GetFiscalYear`)

## Called by

- [Report 5607 "Fixed Asset - Projected Value"](../report/5607.md) (2 calls: `CalculateFirstDeprAmount → Calculate`, `CalculateSecondDeprAmount → Calculate`)
- [Codeunit 5632 "FA Jnl.-Post Line"](../codeunit/5632.md) (1 call: `PostDeprUntilDate → Calculate`)
- [Codeunit 5642 "FA Reclass. Transfer Line"](../codeunit/5642.md) (1 call: `CalcDB1DeprAmount → Calculate`)

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