A dimension is a characteristic of the items in the matrix, such as size, color, style, or format. A matrix item can have up to three dimensions.

Dimensions have attributes and codes:  An attribute is the value of the dimension. For example, the attributes for a Size dimension might be Small, Medium, and Large. Each attribute needs a short attribute code, such as SM, MD, and LG. To arrange the attributes in the list, select the attribute you want to move, and then use the arrow buttons to move it up or down.

Dimension Sets: A dimension set is a saved dimension, including its attributes and attribute codes. To load a previously created dimension set, click the magnifying glass next to the appropriate Dimension box when adding the matrix item on the Component Item tab. 

To Add Component Items and Component Sets:

1.    Select Wizards, New Item Wizard
2.    Under type, select Matrix
3.    Highlight the Lookup Code field and it will pop up the Item Matrix Properties screen
4.    Type in the Lookup Code, the description and the other information on the General tab
5.    Select the Component Item tab
6.    Select the Magnifying glass next to Dimension 1
7.    Select New and type a description for the dimension set (ex. Size, Flavor)
8.    Under Attributes type the values (ex. Small for size, Strawberry for flavor)
9.    Under code, enter a small value that the system will recognize the attribute (ex. S for Small)
10.    Repeat for Dimensions 2 and 3 if necessary
11.    After you click Create Components, a dialog box will appear where you can specify how the lookup codes and descriptions of the component items will look. Component item lookup codes and descriptions can, if desired, contain information about one or more dimensions (ex. Small Red Sweatshirt)
12.    The items and their properties will populate the Component Item table
13.    Select Choose columns to further distinguish the items
14.    If there are items that are created that aren't going to be in inventory, highlight that item in the table and select remove and it will remove it from the Component Item table
15.    When all information in the table is as desired, select the quantity view tab. 
Note:  This will actually save the item's properties in the database, so ensure the information is correct

16.    Determine all quantities necessary for each item, including on hand, committed, on order
