Rules for Event Rules
An upgrade preserves these changes:
For APPL, all retrofitting is done using the Visual FDA and ER Merge tools.
Custom event rules on a new custom control field.
For reports, tables, and business function events that do not have any event rules attached to the same event.
An upgrade replaces modifications to applications, reports, tables, and business functions events that have existing event rules.
Use the Visual ER tools to restore custom event rules.
