Invalid Master/Detail Join. A child row has multiple parents

6 August 2005

Issue Description

While attempting to preview an object in the AnyView IDS Console the following message is presented:

 

Invalid Master/Detail Join.  A child row has multiple parents

 

This error indicates that the join type that was selected in the "Join Components" tab of the "Object Maintenance" window is creating a relationship that cannot validly be displayed in a hierarchical (parent/child) fashion.

 

Solution

This error can be corrected from the "Join Components" tab by selecting one of the two available 'Flat' join menu options.  To do so:

 

1)      From the "Object Maintenance" window in the AnyView IDS Console, select the "Join Components" tab.

2)      Right-click on  the join line between the components and select either:

 

Flat Object Equal Join

 

Or

 

Flat Object Left Outer Join

 

3)      Click on the "Preview" tab to see the object displayed.

 

Note: If you are joining more than two components, you may need to change several of your join types to be 'flat' joins.
