|  | Description | `ReservEntry.Description` | Specifies a description of the reservation in the window. |
|  | Quantity to Reserve | `QtyToReserveBase` | Specifies the total quantity of the item that must be reserved for the line. |
|  | Reserved Quantity | `QtyReservedBase` | Specifies the quantity of the item reserved for the line. |
|  | Unreserved Quantity | `QtyToReserveBase - QtyReservedBase` | Specifies the difference between the Quantity to Reserve field and the Reserved Quantity field. |
| Control1 | Summary Type | [Summary Type](../table/338.md#fields) | Specifies which type of line or entry is summarized in the entry summary. <small>from the table field</small> |
|  | Total Quantity | `ReservMgt.FormatQty(Rec."Total Quantity")` | Specifies the total quantity of the item in inventory. |
|  | Total Reserved Quantity | `ReservMgt.FormatQty(Rec."Total Reserved Quantity")` | Specifies the total quantity of the item that is reserved on documents or entries. |
|  | Qty. Allocated in Warehouse | `ReservMgt.FormatQty(Rec."Qty. Alloc. in Warehouse")` | Specifies the quantity of the item that is allocated to activities in the warehouse. |
|  | Reserved Qty. on Picks and Shipments | `ReservMgt.FormatQty(Rec."Res. Qty. on Picks & Shipmts.")` | Specifies the sum of the overlap quantities. |
|  | Total Available Quantity | `ReservMgt.FormatQty(Rec."Total Available Quantity")` | Specifies the quantity that is available for the user to reserve from entries of the type. |
|  | Non-specific Reserved Qty. | [Non-specific Reserved Qty.](../table/338.md#fields) | Specifies the quantity of the item that is reserved but does not have specific item tracking numbers in the reservation. <small>from the table field</small> |
|  | Current Reserved Quantity | `ReservMgt.FormatQty(ReservedThisLine(Rec))` | Specifies how many items in the entry are reserved for the line opened in the Reservation window. |
| Content | NoteText | label | — |
| Filters | Variant Code | `ReservEntry."Variant Code"` | Specifies the variant code for the reservation. |
|  | Location Code | `ReservEntry."Location Code"` | Specifies the location code for the reservation. |
|  | Serial No. | `ReservEntry."Serial No."` | Specifies the serial number for an item in the reservation. |
|  | Lot No. | `ReservEntry."Lot No."` | Specifies the lot number for the reservation. |
|  | Package No. | `ReservEntry."Package No."` | Specifies the package number for the reservation. |

## Actions

| Group | Action | ToolTip | Runs |
|---|---|---|---|
| Line | Available to Reserve | View all the quantities on documents or in inventory that are available to reserve for the item on the line. The two actions, Auto Reserve and Reserve from Current Line make reservations from the quantities in this view. |  |
|  | Reservation Entries | View all reservations that are made for the item, either manually or automatically. |  |
| Functions | Auto Reserve | Automatically reserve the first available quantity for the item on the line. |  |
|  | Reserve from Current Line | Open the view of quantities available to reserve and select which to reserve. |  |
|  | Cancel Reservation from Current Line | Cancel the selected reservation entry. |  |

## 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) (6 calls: `AutoReserve → AutoReserve`, `DrillDownTotalQuantity → IsPositive`, `FilterReservEntry → IsPositive`, …)
- [Codeunit 5402 "Unit of Measure Management"](../codeunit/5402.md) (2 calls: `GetSerialLotNo → QtyRndPrecision`, `UpdateReservFrom → QtyRndPrecision`)
- [Codeunit 99000830 "Create Reserv. Entry"](../codeunit/99000830.md) (2 calls: `GetSerialLotNo → SignFactor`, `ReservedThisLine → SignFactor`)
- [Page 497 "Reservation Entries"](../page/497.md) (2 calls: `DrillDownReservedQuantity → (object)`, `DrillDownReservedThisLine → (object)`)
- [Codeunit 6500 "Item Tracking Management"](../codeunit/6500.md) (1 call: `GetSerialLotNo → SumUpItemTracking`)
- [Page 6507 "Item Tracking List"](../page/6507.md) (1 call: `GetSerialLotNo → (object)`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24-25, BC27-28

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: "Reservation")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
