A very common practice is to add properties to existing repository items, for instance by extending the product catalog. The example in this section describes in detail the changes you would need to make if you had added a new attribute, weight, to the SKUs in your catalog. The example assumes that you have already made this change to your repository, and now want to include weight information in your reports.

To add an attribute to a dimension:

<item-descriptor name="sku">
  <table name="ARF_SKU">
    <property name="weight" column-name="WEIGHT" type="double"/>
