A category is a label assigned to a group of code conversion rules in the Code Conversion Values window. For example, the UOM category contains all unit of measure code conversion rules.

All desired categories, such as unit of measure or carrier code, must be defined. Any category can be used in several transactions, or several times within a single transaction.

You can use a code conversion category from the e-Commerce Gateway's predefined list or you can define your own code conversion category.

Once defined, code conversion categories must be assigned to table columns to activate the code conversion for the specific data element. You do this in the Assign Categories window.

To define additional code conversion categories:

1. Navigate to the Code Conversion Categories window.

2. Enter the category code and description.

3. To assign code conversion values to key attributes (such as a trading partner), enable one or more search keys.

   For example, if you want to set the first search key to "X12," you must enable Search Key 1. The actual search criteria are entered in the Assign Categories window. The actual code conversion values and search key values are defined in the Code Conversion Values window.
