Prerequisites
If you change a
report definition or a set that is used in a report definition, you must regenerate all report groups that contain the report. When a report and/or set definition within a report group is changed, the report group is flagged; when you attempt to execute the flagged report group, the system prompts you to regenerate the report group before the system executes it. Once the report group has been regenerated, the report will reflect your changes.Procedure
The Change Report: Initial Screen appears.
– The library name of the report definition you want to change
– The name of the report definition you want to change

For Report Writer reports you can use the function Utilities ® Layout control to view your changed report, without data having to be loaded. For more information, see
