When you generate a Bill of Material, Smart Instrumentation calculates the total quantity of hook-up items according to the following formula: (number of associated instrument tags + number of additional tags for the Bill of Material) × quantity of items of the same type × (item spares percentage + 100) / 100. For example, if the total number of control valves associated with the hook-ups in the Bill of Material is 5, the number of additional instruments is 2, the quantity of male connector items is 2, and spares percentage is 20%, the total quantity is calculated as (5 + 2) × 2 × (20 +100) / 100 and the Total Qty column in the Bill of Material displays 12.

  • If the unit of measure of the hook-up item is either Item or Piece, the software rounds up the calculated total quantity value so that no fraction remains.

  • You define the number of the additional tags on the Associate Tag Numbers with Hook-Ups dialog.

  • You define the item quantity and spares percentage on the Associate Items with Hook-Ups dialog. It is also possible to define item spares percentage on the Hook-Up Item Properties dialog.
