Units - Selling Items by Area or Volume

In this example, the Items are fabrics that are sold by the square metre. Follow these steps:
  1. Create a Unit "M2" (or square metre) in which the Check Size Entry box is marked and the Two Dimensions option is selected.

  2. In your Item records, enter "M2" as the Unit. Since the Item is sold by the square metre, the Width, Height and Depth fields can be left blank. The Base and Cost Prices should be figures for one square metre.

  3. When the Item is sold, enter the appropriate quantity either to the Quantity field on flip A of the Invoice or to the Unit Qty field on flip E. In the latter case, the Quantity on flip A will be calculated to show the area in square metres and the pricing will be adjusted accordingly.
Certain fabrics might not be sold by the square metre. For example, the basic measurement of a particular fabric might be five metres by two. In this case, you can either create a Unit for this size and proceed as described above, or you can use the "M2" Unit as follows:
  1. In the Item record, enter 5 as the Width and 2 as the Height. The Base and Cost Prices should still be figures for one square metre, because that is the Unit.

  2. When the Item is sold, do not enter anything to the Quantity field on flip A of the Invoice. Instead, enter the appropriate quantity to the Unit Qty field on flip E. This should be the quantity of 5 x 2 sheets of fabric purchased by the Customer. The Quantity on flip A will be calculated to show the area in square metres and the pricing will be adjusted accordingly.
Some products might be sold by the square or cubic metre, but they might not be of a uniform size or shape. An example might be stone. Follow these steps:
  1. Check the Enable Quantity Calculation box in the Item Settings setting.

  2. Create a Unit "M3" (or cubic metre) in which the Check Size Entry and Calculate Quantity boxes are marked and the Three Dimensions option is selected.

  3. In your Item records, enter "M3" as the Unit. Since the Item is sold by the cubic metre, the Width, Height and Depth fields can be left blank. The Base and Cost Prices should be figures for one cubic metre.

  4. When the Item is sold, enter the appropriate dimensions to the Width, Height and Depth fields on flip E of the Invoice row. The Quantity on flip A will be calculated to show the area in square metres and the pricing will be adjusted accordingly. Since the Check Size Entry box in the Unit record has been marked, you will not be able to save the Invoice if you fail to enter figures in all three measurement fields (Hansa will display the error message: "Invalid Size for the Item").
These examples also apply to Orders (flip H) and Quotations (flip E). The third example also applies to Deliveries (flip E), Goods Receipts (flip G) and Productions (flip C).
