These subjects are dealt with here:

• General information on variants
• Creating variants
• Displaying/maintaining variants
• Deleting variants

A variant refers to the definition of an entity type, that is, you can assign several definitions to an entity type using variants.

It is possible, therefore, for an entity type to have a number of different definitions in the modeling process, particularly if the entity type is being used by more than one developer.

The first definition of an entity type, which is also its first variant, is assigned the ID number 00. The ID numbers for the other variants are incremented in each case by 1.

If you wish to display or change an entity type for which variants have been created, enter the name of the entity type and activate either Display or Change to display all the variants together with their corresponding ID numbers in a dialog box. Choose the required variant in this dialog box.
