Defining units of measure
Unit of measure is an attribute of the item. In Structure Manager, you specify the value of the Quantity occurrence property in the units of measure for the component item (for example, 1.5 L for an Oil item). Alternatively, you can specify the unit of measure as each, that is, a numerical value. In this case, you must specify the value as a whole number (for example, 500). You can optionally specify a quantity for a structure line in a user-defined unit of measure. You cannot change the unit of measure after any revision of the item is released or is used in the structure.
Note When you add a line to the structure, its unit of measure (UOM) is initially the same as the default UOM for the corresponding item type. You can subsequently change the UOM of the line, if appropriate. If the default UOM of the item is not each, you cannot change the UOM of the line to each. Teamcenter considers the UOM of the line when displaying a quantity value. If the UOM of the line is each, it displays the quantity value as an integer; otherwise, it displays a floating (real) value. By default, Teamcenter displays quantities with a maximum of two decimal places.
