After doing modifications to the Data Model it is important to validate the status of the relationships between the business objects added to the model.

Steps

  1. Go to the Status Report tab
  2. Click on the Reload button at the right corner
  3. Validate that there are no exceptions under the Attributes and Relationships columns.
  4. Expand the Objects and check that all the fields have a Status OK.
  5. If find exceptions or errors depending on the message maybe you need to do a deployment to make active the changes or just check the model for any misconfiguration.
