Maintain Alternates and Interchangeability Codes
Explanation
This activity is used to define new alternates, i.e., template and position 
alternates, or to change the interchangeability code of an existing alternate. 
Since new alternates and/or the change to a current interchangeability code can 
be introduced by a modification, this activity can be used to register these 
changes on the relevant modification.  
Prerequisites
  - The modification must have been created. This modification must be in the
	Preliminary status.
- The template structure must have been created.
System Effects
  - New alternates and/or interchangeability codes are registered. When the 
	modification is set to the Active status, these alternates and/or 
	interchangeability codes can be used for serials.
- If the Allow Alternate Without Modification Compliance check box is 
	selected, the alternate definition will be effective for all serials without 
	having to comply with the modification once the modification is activated.
