To create a Supply Type:

1. Click or select Data > Supply Types.

   The ‘Edit Supply Type’ dialog box is displayed.

2. Click the New button in the top left-hand corner of the dialog box.
3. Enter a meaningful name for the Supply Type in the highlighted box and press Enter.

   In the right-hand pane of the dialog box, a chart is displayed featuring rows of the available Entity Types in your model and columns representing the composition, in percentages, of each as part of the Supply Type.

   
4. There are two ways to add proportions of Entity Types to your Supply Type: click and drag a percentage across the chart or enter values into the appropriate data cells at the foot of each column.

   To click and drag a percentage into the chart, double-click anywhere within the row to the right of the name of an Entity Type. Depending on where you click, this will give you an initial value represented by a coloured bar. Now drag the coloured bar to the correct value. If you'd like to drag the bar in increments of 0.01% rather than 1%, hold down the 'Ctrl' key as you drag.

   or

   To type percentage values directly into the chart, click into the data cell at the foot of a column and enter a percentage.

   Note: The overall percentage of the Entity Types must total 100%. A counter beneath the chart indicates the percentages for your guidance.
5. Click Apply or OK to save the new Supply Type.

   It is added to the ‘Data’ tab of LEGION Model Builder Object Directory, under Supply Type. A completed Supply Type will resemble the following.
