Layout controls in source order, grouped by the container they sit in. Shows: the table field a control is bound to (or its expression as written); ToolTip: the control's own, else the bound field's (marked).

| Group | Control | Shows | ToolTip |
|---|---|---|---|
| Control1 | Transfer-from Code | [Transfer-from Code](../table/5741.md#fields) | Specifies the code of the location that items are transferred from. <small>from the table field</small> |
|  | Transfer-to Code | [Transfer-to Code](../table/5741.md#fields) | Specifies the code of the location that the items are transferred to. <small>from the table field</small> |
|  | Shipment Date | [Shipment Date](../table/5741.md#fields) | Specifies when items on the document are shipped or were shipped. A shipment date is usually calculated from a requested delivery date plus lead time. <small>from the table field</small> |
|  | Receipt Date | [Receipt Date](../table/5741.md#fields) | Specifies the date that you expect the transfer-to location to receive the items on this line. |
|  | Quantity (Base) | [Quantity (Base)](../table/5741.md#fields) | Specifies the quantity on the line expressed in base units of measure. |
|  | Reserved Qty. Inbnd. (Base) | [Reserved Qty. Inbnd. (Base)](../table/5741.md#fields) | Specifies the quantity of the item reserved at the transfer-to location, expressed in base units of measure. |
|  | Reserved Qty. Outbnd. (Base) | [Reserved Qty. Outbnd. (Base)](../table/5741.md#fields) | Specifies the quantity of the item reserved at the transfer-from location, expressed in the base unit of measure. |
|  | Available Quantity | `QtyToReserveBase` | Specifies the quantity of the item that is available. |
|  | Current Reserved Quantity | `GetReservedQtyInLine()` | Specifies the quantity of the item that is reserved for the document type. |

## Actions

| Group | Action | ToolTip | Runs |
|---|---|---|---|
| Functions | Reserve | Reserve the quantity that is required on the document line that you opened this window for. |  |
|  | Cancel Reservation | Cancel the reservation that exists for the document line that you opened this window for. |  |

- `OnAfterUpdateReservFrom(var ReservationEntry: Record "Reservation Entry")` (integration)
- `OnAfterUpdateReservMgt(var ReservationEntry: Record "Reservation Entry")` (integration)

## Procedures

- `SetSource(CurrentSourceRecRef: RecordRef; CurrentReservEntry: Record "Reservation Entry"; Direction: Enum "Transfer Direction")`
- `GetReservedQtyInLine(): Decimal` (protected)

## Relations

- source table [Table 5741 "Transfer Line"](../table/5741.md)

## 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 99000845 "Reservation Management"](../codeunit/99000845.md) (4 calls: `CreateReservation → CreateReservation`, `GetReservedQtyInLine → MarkReservConnection`, `SetSourceTableFilters → GetAvailabilityFilter`, …)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24

## Documented on Microsoft Learn

- [Get an availability overview](https://learn.microsoft.com/dynamics365/business-central/inventory-how-availability-overview)

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: "page", object_name: "Available - Transfer Lines")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
