Overwrite a report used in a viewer portlet without breaking the portlet..

[prikala]

If you work with Cognos viewer portlets or Cognos Workspaces, you have probably noticed that when you copy a new version of a report over a report that is used in a viewer/workspace, the reference to original is lost (viewer portlet is broken, workspace uses a cached copy of the report).

How do You cope with these situations?
- newer overwrite reports, modify the original
- modify the referencing object after overwrite
- use shortcuts
- use updateTargetObjectWhenOverwrite parameter (http://www-01.ibm.com/support/docview.wss?uid=swg21625148)

I have used first three but the updateTargetObjectWhenOverwrite seems interesting.I wonder if there is anything negative about it?
