An object of type Extract in Predict fulfills two functions:
to group objects logically
to determine the objects to be transferred with the Predict Coordinator.
An object can be contained in a maximum of 32 extracts. The number of objects in an extract is virtually unlimited. An extract can contain other extracts - including itself.
Extracts #SAG-TRANSFER and #SAG-ERROR are created automatically by the Coordinator. See the Predict Coordinator documentation.
In the Predict metastructure, an extract can have passive and active associations of the following types:
| Valid passive association: | "Contained in RT" (association is created automatically) |
| Valid active association: | no predefined association |
When you transfer objects with the Predict Coordinator, a report listing is created automatically and the extract containing the objects to be transferred is linked as a child object to this report listing. See the Predict Coordinator documentation.
The description of object type Extract is organized under the following headings:
| Maintaining Objects of Type Extract |
| Extract-Specific Maintenance Functions |
| Extract Retrieval |
