Consider the following scenario, where a user attempts to modify the Member ID attribute of a Golden Record

Unable to Edit Member ID
Unable to Edit Member ID

The Date of Birth attribute can be edited, however, Member ID cannot. In this instance, editing can be enabled by making a change to Survivorship Rules > Override Rule configuration.  

Survivorship Rule > Override Rule
Survivorship Rule > Override Rule

 In Application Builder, navigate to the Entity > Survivorship Rules. Here, we change the Override Rule from No Override to Override – until next user changes. Save the changes in Application Builder, then use the Refresh applicaton option in the application to propagate changes.  

Editing is now enabled for Member ID

  • The function exists, but you do not have access to it.
  • The function exists, and you have access, but it is not in the search_path.
