Below you will find the report version history. When a report is updated, a new version of the report is created. The report history allows you to see the changes between versions. You can select two versions of the report to compare. The fields that were changed between versions will be highlighted in yellow.
The translation of reports creates two separate versions which is why some reports may not seem to have any differences. In this case, only the language field below will be highlighted in yellow.
