Base Application · Microsoft.Inventory.Availability · BC25-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/Service/Item/ServItemCheckAvail.Codeunit.al) · facts from BC29

## Events published

- `OnServiceInvLineShowWarningOnAfterFindingPrevServiceLineQtyWithinPeriod(ServiceLine: Record "Service Line"; OldServiceLine: Record "Service Line"; var IsHandled: Boolean)` (integration)
- `OnServiceInvLineShowWarningOnBeforeShowWarning(ServLine: Record "Service Line"; var ContextInfo: Dictionary of [Text, Text]; OldServLine: Record "Service Line"; var OldItemNetChange: Decimal; var IsWarning: Boolean; var IsHandled: Boolean)` (integration)
- `OnBeforeServiceInvLineCheck(ServInvLine: Record Microsoft.Service.Document."Service Line"; var Rollback: Boolean; var IsHandled: Boolean)` (integration)

## Procedures

- `ServiceInvLineCheck(ServInvLine: Record "Service Line"): Boolean`
- `ServiceInvLineShowWarning(ServLine: Record "Service Line"): Boolean`
- `RaiseUpdateInterruptedError()`

## 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 311 "Item-Check Avail."](../codeunit/311.md) (6 calls: `RaiseUpdateInterruptedError → RaiseUpdateInterruptedError`, `ServiceInvLineCheck → GetItemAvailabilityNotificationId`, `ServiceInvLineCheck → ShowAndHandleAvailabilityPage`, …)
- [Codeunit 1511 "Notification Lifecycle Mgt."](../codeunit/1511.md) (1 call: `ServiceInvLineCheck → RecallNotificationsForRecordWithAdditionalContext`)

## Called by

- [Codeunit 5923 "Service-Quote to Order"](../codeunit/5923.md) (2 calls: `TransferQuoteToOrderLines → RaiseUpdateInterruptedError`, `TransferQuoteToOrderLines → ServiceInvLineCheck`)
- [Table 5902 "Service Line"](../table/5902.md) (2 calls: `CheckItemAvailable → RaiseUpdateInterruptedError`, `CheckItemAvailable → ServiceInvLineCheck`)
- [Codeunit 6474 "Serv. Item Substitution"](../codeunit/6474.md) (1 call: `ItemServiceSubstGet → ServiceInvLineCheck`)

## Across versions

- Present in: BC25-30
- Changed (declaration) in: BC26

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: "Serv. Item Check Avail.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
