Adding Levels to Hierarchies

You must define at least one level for every hierarchy.

You must define the topmost level first, then the next lower level, and so on.

To add a level, do the following:

1. Enter values in the following fields:
   • Name
   • Description
   • Entry Length. The number of characters allowed for a term in this classification level. The maximum is 300.
   • Term Uniqueness. Select one of the following values to determine the way Oracle LSH enforces the uniqueness requirement for terms in the level:
     • Unique Within Level. Each term contained in this level must be unique relative to other terms in the same level.
     • Unique Within Parent. Each term contained in this level must be unique relative to the other terms in the level that are related to the same parent term.
   • Allow Classification
     • If selected, and if the hierarchy as a whole is set to Active, you can assign this level to object subtypes. Definers can then classify objects of those subtypes to values you define for the level.
     • If cleared, you cannot assign the level to object subtypes and definers cannot classify objects to the level. Oracle LSH uses terms in this level solely as folders in the Reports screen to organize folders in the next lower level.
2. Repeat this procedure to add another level. Click Add Hierarchy Level to add additional rows.
3. Click Apply. The system saves the changes and the Maintain Hierarchy screen appears.

To add a level after you have clicked Apply, click Update.

After creating a hierarchy, you must activate it before you can use it. See Activating the Hierarchy and Making it Usable or Unusable. You can remove and reorder a hierarchy level only if its owning hierarchy is not set to Active.

This section contains the following topics:

• Reorder Hierarchy Levels
  To change the order of the levels in a hierarchy, do the following:
• Remove Hierarchy Levels
  To remove a level, select it and click Remove.
