Obsolete Codes
Codes may only need to be used for a limited time. When these codes are no longer needed, they are made obsolete. Making a code obsolete does not delete the code, but it does remove the code from the list of available codes on a code page. Codes can only be made obsolete from the location where the code was created.
The following options are available to make codes obsolete:
•  Right-click the code you want to hide on the code page, and select Obsolete Today.
•  Select the code from the list to access the code information, and enter a date in the Obsolete Date field.
When codes with obsolete dates are shown in the code list, Image is displayed beside the code to indicate that an obsolete date is entered. Pause your mouse pointer on this icon to see the obsolete date.
