When you attempt to validate a Cognos 8 Framework Manager model Framework Manager is working to detect various problems, such as invalid objects and their status. Framework Manager validates four main items in the model:
1. Invalid Relationships
Framework Manager identifies query subjects whose relationships are invalid, so that you can delete them. Invalid relationships include:
- many-to-many relationships
- orphaned query subjects (query subjects with no relationships)
- multiple relationships (or relationship shortcuts) between query subjects (or query subject shortcuts)
If you do not define relationships for a model query subject because it uses the relationships defined for the data source query subject, an error is listed when you check the project. You can define relationships for the model query subject, or you can leave the model query subject as an orphan.
2. Invalid References
Invalid references exist when an object references another object to which it does not have access or which no longer exists in the project.
3. Invalid Object Definition
Framework Manager warns you when your changes to an object will mean it cannot be executed. If you proceed, these are marked as invalid. When you verify a project, Framework Manager identifies any query subjects, shortcuts, filters, calculations, and relationships that were previously marked as invalid so that you can repair them.
4. Invalid Aggregation Rules
Framework Manager identifies any aggregate settings that are invalid for the data type of the query items to which they are applied. For example, if Product_Name has a character data type, its aggregate property cannot be set to either sum, count, or average. To repair the error, Framework Manager resets the aggregate property to unsupported.
