## Fields on this page

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 |
|---|---|---|---|
| Group | Document Type | [Document Type](../table/901.md#fields) | Specifies the type of assembly document that the assembly order header represents in assemble-to-order scenarios. <small>from the table field</small> |
|  | Document No. | [Document No.](../table/901.md#fields) | Specifies the number of the assembly order header that the assembly order line refers to. <small>from the table field</small> |
|  | Type | [Type](../table/901.md#fields) | Specifies if the assembly order line is of type Item or Resource. <small>from the table field</small> |
|  | No. | [No.](../table/901.md#fields) | Specifies the number of the involved entry or record, according to the specified number series. <small>from the table field</small> |
|  | Variant Code | [Variant Code](../table/901.md#fields) | Specifies the variant of the item on the line. <small>from the table field</small> |
|  | Description | [Description](../table/901.md#fields) | Specifies the description of the assembly component. <small>from the table field</small> |
|  | Description 2 | [Description 2](../table/901.md#fields) | Specifies the second description of the assembly component. <small>from the table field</small> |
|  | Shortcut Dimension 1 Code | [Shortcut Dimension 1 Code](../table/901.md#fields) | Specifies the code for Shortcut Dimension 1, which is one of two global dimension codes that you set up in the General Ledger Setup window. <small>from the table field</small> |
|  | Shortcut Dimension 2 Code | [Shortcut Dimension 2 Code](../table/901.md#fields) | Specifies the code for Shortcut Dimension 2, which is one of two global dimension codes that you set up in the General Ledger Setup window. <small>from the table field</small> |
|  | Location Code | [Location Code](../table/901.md#fields) | Specifies the location from which you want to post consumption of the assembly component. <small>from the table field</small> |
|  | Bin Code | [Bin Code](../table/901.md#fields) | Specifies the code of the bin where assembly components must be placed prior to assembly and from where they are posted as consumed. <small>from the table field</small> |
|  | Unit of Measure Code | [Unit of Measure Code](../table/901.md#fields) | Specifies how each unit of the item or resource is measured, such as in pieces or hours. By default, the value in the Base Unit of Measure field on the item or resource card is inserted. <small>from the table field</small> |
|  | Quantity per | [Quantity per](../table/901.md#fields) | Specifies how many units of the assembly component are required to assemble one assembly item. <small>from the table field</small> |
|  | Quantity | [Quantity](../table/901.md#fields) | Specifies how many units of the assembly component are expected to be consumed. <small>from the table field</small> |
|  | Consumed Quantity | [Consumed Quantity](../table/901.md#fields) | Specifies how many units of the assembly component have been posted as consumed during the assembly. <small>from the table field</small> |
|  | Remaining Quantity | [Remaining Quantity](../table/901.md#fields) | Specifies how many units of the assembly component remain to be consumed during assembly. <small>from the table field</small> |
|  | Due Date | [Due Date](../table/901.md#fields) | Specifies the date when the assembly component must be available for consumption by the assembly order. <small>from the table field</small> |
|  | Reserved Quantity | [Reserved Quantity](../table/901.md#fields) | Specifies how many units of the assembly component have been reserved for this assembly order line. <small>from the table field</small> |
|  | Qty. per Unit of Measure | [Qty. per Unit of Measure](../table/901.md#fields) | Specifies the quantity per unit of measure of the component item on the assembly order line. <small>from the table field</small> |

## Called by

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 5997 "Assembly Warehouse Mgt."](../codeunit/5997.md) (2 calls: `OnShowSourceDocLine → (object)`, `ShowAssemblyLine → (object)`)
- [Codeunit 926 "Assembly Line-Reserve"](../codeunit/926.md) (2 calls: `OnLookupLine → (object)`, `ShowSourceLines → (object)`)

## 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: "Assembly Lines")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
