Propagating Changes to Objects After the Merge
If you do not select an upgrade ancestor for an object, then changes to the upgrade ancestor are not propagated to the descendant during the repository merge.
You can manually propagate changes to descendants after the merge by using the Siebel Tools object comparison and synchronization features. These features enable you to compare any two objects and propagate differences to one or both of the objects. For more information, see Configuring Siebel Business Applications and About the Siebel Repository Merge.
