| 3 | Qty. per Unit of Measure | Decimal | Specifies how many of the base unit of measure are contained in one unit of the item. |  |
| 4 | Qty. Rounding Precision | Decimal | — |  |
| 721 | Coupled to Dataverse | Boolean | Specifies that the item unit of measure is coupled to a unit of measure in Dynamics 365 Sales. | FlowField: exist("CRM Integration Record" where("Integration ID" = field(SystemId), "Table ID" = const(Database::"Item Unit of Measure"))) |
| 7300 | Length | Decimal | Specifies the length of one item unit when measured in the specified unit of measure. |  |
| 7301 | Width | Decimal | Specifies the width of one item unit when measured in the specified unit of measure. |  |
| 7302 | Height | Decimal | Specifies the height of one item unit when measured in the unit of measure in the Code field. |  |
| 7303 | Cubage | Decimal | Specifies the volume (cubage) of one item unit in the unit of measure in the Code field. |  |
| 7304 | Weight | Decimal | Specifies the weight of one item unit when measured in the specified unit of measure. |  |

## 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: "table", object_name: "Item Unit of Measure")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
