Splitting and Merging Classes

You can reorganize your classification system by splitting or merging classes.

• The characteristics structure of the classes must be identical

• If the classes have different class types, the objects cannot be classified in any classes of the target class type except for the target class itself

• You can only split and merge classes that do not have a variant class type or a class type in which you can classify objects of different types

• The classes can have different class types

• If the class is part of a class hierarchy and the objects have inherited characteristics, the inherited characteristics are deleted from the classification when you reassign the objects

• If an object to be reassigned has been classified in more than one class, the classifications in these other classes are not affected by the reorganization

• Assignments of classes to the class are not changed. These remain in the initial class. Only assigned objects that are not classes are reassigned.

Merging Classes

When you merge classes, all the objects assigned to the first class (the one you enter in the From class field) are reassigned to the second class (the one you enter in the To class field) and deleted from the first class. However, the first class still exists after you have reassigned the objects.

To merge the objects of two classes, proceed as follows:

1. From the Classification System menu, choose  Environment  Reorganization  Split/merge. 

2. Select Merge.

3. Enter the class you want to merge with another class and the class type under Source.

   Enter the class and select a class type under Target.

   If you want to merge the classes on a specific date, enter a change number with the date you require.

4. Choose Execute .

You see a message telling you that the objects have been reassigned.

Splitting Classes

When you split a class, all the objects you select from the first class (the one you enter in the From class field) are reassigned to the second class (the one you enter in the To class field) and deleted from the first class.

To assign specific objects from one class to another class, proceed as follows:

1. Choose  Environment  Reorganization  Split/merge. 

2. Select Split .

3. In the From class field, enter the class from which you want to delete objects.

   In the To class field, enter the class to which you want to assign the objects.

   Enter the class type of both classes.

   If you want to split the class on a specific date, enter a change number with the date you require.

4. Choose Execute .

5. You see the value assignment screen of the initial class. You can use the values to find the objects you want to reassign to the target class.

6. Choose Find in initial class.

7. You see the search result. In the search result, you can select the objects you want to reassign to the target class.

8. Choose Copy .

You see a message telling you that the selected objects have been reassigned to the target class.
