Modifications to Existing Fields
You can modify some existing property fields and any custom fields that have been created. The property fields that can be modified are always enumerated types.
For example, 
		Priority is an existing change request property that can be customized. On the 
		Synopsis tab of the 
		Change Request Properties dialog box, 
		Priority has the values 
		Yes and 
		No, but is implemented as an enumerated type with 
		Yes having the numeric code of 
		1 and 
		No having the numeric code of 
		0. If your company prefers to prioritize change requests on a scale from 1 (high) to 10 (low), you can add additional values. You can use the current numeric codes 0 and 1 with new names or disable them.
	 
Tip: Try to take advantage of the existing codes in some way. {TheNote
For example, you might change the name of the enumerated value 
		No to 
		Not Prioritized. Then you can query for 
		Priority equal to 0 to identify the change requests that need to be prioritized.
	 
You might also change the name 
		Yes to 
		Priority 1, as it already has the code 
		1. Then you can add additional values for 
		Priority 2 
		through 
		Priority 10. Any numeric codes that you assign must have a value greater than 100, because the application reserves the values 0 through 100 for internal uses. So you might add a value with the name 
		Priority 2 
		 and the numeric code 
		101, 
		Priority 3 with the numeric code 
		102, and so on.
	 
Tip: Queries use the numeric codes to make comparisons based on enumerated values. Using the above codes, you can write a query to locate Priorities 1, 2, and 3, by querying for 
		Priority greater than 0 and less than 103.
By default, sort and list boxes display items in the order that they appear in the Add Field or Modify Field dialog boxes. You can use the sort options to sort by name in ASCII or alphabetical order.
