## 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 |

| Control1 | 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> |
|  | Inventory | `Inventory` | Specifies how many units of the assembly component are in inventory. |
|  | Gross Requirement | `GrossRequirement` | Specifies the total demand for the assembly component. |
|  | Scheduled Receipt | `ScheduledRcpt` | Specifies how many units of the assembly component are inbound on orders. |
|  | Expected Available Inventory | `ExpectedInventory` | Specifies how many units of the assembly component are available for the current assembly order on the due date. |
|  | Current Quantity | [Remaining Quantity](../table/901.md#fields) | Specifies how many units of the component are required on the assembly order line. |
|  | 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> |
|  | Current 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> |
|  | Earliest Available Date | `EarliestDate` | Specifies the late arrival date of an inbound supply order that can cover the needed quantity of the assembly component. |
|  | Able to Assemble | `AbleToAssemble` | Specifies how many units of the assembly item on the assembly order header can be assembled, based on the availability of the component. |
|  | Lead-Time Offset | [Lead-Time Offset](../table/901.md#fields) | Specifies the lead-time offset that is defined for the assembly component on the assembly BOM. <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.

## Ask your agent

Procedure bodies are not stored here (D10). 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 Line Avail.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
