|---|---|---|---|
| General | Start Date | `StartDate` | Specifies the start date of the period for which you want to calculate demand. |
|  | End Date | `EndDate` | Specifies the end date of the period for which you want to calculate demand. Enter a date that is later than the start date. |

|  | Description | [Description](../table/5830.md#fields) | Specifies the description of the item for which availability is being calculated. <small>from the table field</small> |
|  | Location Code | [Location Code](../table/5830.md#fields) | Specifies the location code of the item for which availability is being calculated. <small>from the table field</small> |
|  | Variant Code | [Variant Code](../table/5830.md#fields) | Specifies the variant of the item on the line. <small>from the table field</small> |
|  | Quantity | `QuantityText` | Specifies how many units of the item are demanded. |
|  | Reserved Quantity | `ReservedQuantityText` | Specifies how many units of the demanded item are reserved. |
|  | Running Total | [Running Total](../table/5830.md#fields) | Specifies the total count of items from inventory, supply, and demand. <small>from the table field</small> |

## Procedures

- `InitTempTable()`

## Triggers

OnAfterGetRecord, OnInit, OnOpenPage

## Relations

- source table [Table 5830 "Availability Calc. Overview"](../table/5830.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 5830 "Calc. Availability Overview"](../codeunit/5830.md) (6 calls: `ExpandAll → CalculateDate`, `ExpandAll → CalculateItem`, `ExpandAll → EntriesExist`, …)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC25, BC28

## Documented on Microsoft Learn

- [Track Relations Between Demand and Supply](https://learn.microsoft.com/dynamics365/business-central/production-how-track-demand-supply)

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