## Events published

- `OnBeforeShowItemAvailabilityFromReqLine(var Item: Record Item; var ReqLine: Record Microsoft.Inventory.Requisition."Requisition Line"; AvailabilityType: Enum "Item Availability Type")` (integration)
- `OnAfterTransferFromPlanProdComp(var InventoryEventBuffer: Record "Inventory Event Buffer"; PlanningComponent: Record "Planning Component"; RequisitionLine: Record "Requisition Line")` (integration)
- `OnAfterTransferFromReqLineTransDemand(var InventoryEventBuffer: Record "Inventory Event Buffer"; RequisitionLine: Record "Requisition Line")` (integration)
- `OnAfterTransferFromReqLine(var InventoryEventBuffer: Record "Inventory Event Buffer"; RequisitionLine: Record Microsoft.Inventory.Requisition."Requisition Line")` (integration)

## Event subscriptions

- OnAfterMakeEntries subscribes to Page "Item Availability Line List" OnAfterMakeEntries
- OnAfterLookupEntries subscribes to Page "Item Availability Line List" OnAfterLookupEntries

## Procedures

- `ShowItemAvailabilityFromReqLine(var ReqLine: Record "Requisition Line"; AvailabilityType: Enum "Item Availability Type")`
- `TransferFromPlanProdComp(var InventoryEventBuffer: Record "Inventory Event Buffer"; PlngComp: Record "Planning Component")`
- `TransferFromReqLineTransDemand(var InventoryEventBuffer: Record "Inventory Event Buffer"; ReqLine: Record "Requisition Line")`
- `TransferFromReqLine(var InventoryEventBuffer: Record "Inventory Event Buffer"; ReqLine: Record "Requisition Line"; AtLocation: Code[10]; AtDate: Date; DeltaQtyBase: Decimal; RecID: RecordID)`

Plus 1 local procedures.

## 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 353 "Item Availability Forms Mgt"](../codeunit/353.md) (8 calls: `ShowItemAvailabilityFromReqLine → FilterItem`, `ShowItemAvailabilityFromReqLine → SetForecastName`, `ShowItemAvailabilityFromReqLine → ShowItemAvailabilityByBOMLevel`, …)

## Called by

- [Codeunit 5530 "Calc. Item Availability"](../codeunit/5530.md) (3 calls: `GetPlanningComponents → TransferFromPlanProdComp`, `GetPlanningLines → TransferFromReqLine`, `GetPlanningTransDemand → TransferFromReqLineTransDemand`)

## Across versions

- Present in: BC25-30
- 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: "Req. Line Availability Mgt.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
