When you modify a model, certain changes may break reports that are associated with the model. Such model changes are:
- Deleting an entity, attribute or relation.
- Modifying the Cardinality property of a model's relation.
 |
Note: It is recommended that you hide an entity or an attribute of the model instead of deleting it. This way, the entity or attribute is not available for use in new reports, but existing reports are not broken. |
When you save a change that breaks a report, a warning appears below the work area for each broken report.
The "ReportName" report was broken by your changes, therefore it is still bound to the old version of this model so that users can view this report without errors. For more information about this warning, see the "Model Breaking Changes" topic in the help.
