## Events published

- `OnBeforeGetFiscalYear(DeprBookCode: Code[10]; EndingDate: Date; var FiscalYearStartDate: Date; var IsHandled: Boolean)` (integration)

## Procedures

- `GetFiscalYear(DeprBookCode: Code[10]; EndingDate: Date): Date`
- `CalculateDate(StartingDate: Date; NumberOfDays: Integer; Year365Days: Boolean): Date`

Plus 1 local procedures.

## Triggers

OnRun

## 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.

- [Report 5607 "Fixed Asset - Projected Value"](../report/5607.md) (4 calls: `GetNextDate → CalculateDate`, `GetPeriodEndingDate → CalculateDate`, `TransferValues → CalculateDate`, …)
- [Codeunit 5610 "Calculate Depreciation"](../codeunit/5610.md) (1 call: `CheckDeprDaysInFiscalYear → GetFiscalYear`)
- [Codeunit 5611 "Calculate Normal Depreciation"](../codeunit/5611.md) (1 call: `CalcDBSLAmount → GetFiscalYear`)
- [Codeunit 5616 "Depreciation Calculation"](../codeunit/5616.md) (1 call: `DeprInFiscalYear → GetFiscalYear`)
- [Table 5612 "FA Depreciation Book"](../table/5612.md) (1 call: `CalcEndingDate → CalculateDate`)

## 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: "FA Date Calculation")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
