Base Application · Microsoft.Inventory.Tracking · BC27-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/Assembly/Inventory/Tracking/AsmReservCheckDateConfl.Codeunit.al) · facts from BC29

## Events published

- `OnAssemblyHeaderCheckOnBeforeIssueError(var ReservationEntry: Record "Reservation Entry"; AssemblyHeader: Record "Assembly Header"; var ForceRequest: Boolean; var IsHandled: Boolean)` (integration)
- `OnAssemblyHeaderCheckOnBeforeUpdateDate(var ReservationEntry: Record "Reservation Entry"; AssemblyHeader: Record "Assembly Header"; var IsHandled: Boolean)` (integration)
- `OnAssemblyLineCheckOnBeforeUpdateDate(var ReservationEntry: Record "Reservation Entry"; AssemblyLine: Record "Assembly Line"; var IsHandled: Boolean)` (integration)

## Procedures

- `AssemblyHeaderCheck(AssemblyHeader: Record "Assembly Header"; ForceRequest: Boolean)`
- `AssemblyLineCheck(AssemblyLine: Record "Assembly Line"; ForceRequest: Boolean)`

## 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 99000815 "Reservation-Check Date Confl."](../codeunit/99000815.md) (8 calls: `AssemblyHeaderCheck → (object)`, `AssemblyHeaderCheck → DateConflict`, `AssemblyHeaderCheck → IssueError`, …)
- [Codeunit 99000845 "Reservation Management"](../codeunit/99000845.md) (6 calls: `AssemblyHeaderCheck → AutoTrack`, `AssemblyHeaderCheck → ClearSurplus`, `AssemblyHeaderCheck → SetReservSource`, …)
- [Codeunit 925 "Assembly Header-Reserve"](../codeunit/925.md) (1 call: `AssemblyHeaderCheck → FindReservEntry`)
- [Codeunit 926 "Assembly Line-Reserve"](../codeunit/926.md) (1 call: `AssemblyLineCheck → FindReservEntry`)

## Called by

- [Codeunit 945 "Asm. Carry Out Action"](../codeunit/945.md) (1 call: `AsmOrderChgAndReshedule → AssemblyLineCheck`)
- [Table 900 "Assembly Header"](../table/900.md) (1 call: `ValidateDueDate → AssemblyHeaderCheck`)
- [Table 901 "Assembly Line"](../table/901.md) (1 call: `VerifyReservationDateConflict → AssemblyLineCheck`)

## Across versions

- Present in: BC27-30
- 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: "Asm. ReservCheckDateConfl")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
