Step 4: Identify Groups of Variables
In this step you identify groups of variables, or variable types, in your messages (for
example, account numbers). It is important to understand that a single variable type can
occur in any number of event messages (for example, account number).
In the sample event messages there are eight types or groups of variables:
1. Name
2. Location
3. Account number
4. Hardware component
5. Hardware subcomponent
6. Serial number
7. Sense status
8. Retry limit
The variables from the messages are shown below in the appropriate group.
