4. Report level and element-Level Property Configuration
From 6.2 and 6.2.1, both report level and individual element-level property configuration support has been added in canned report. There are hundreds of such kind of properties which exists which can be used to specify the behavior of the application, export controls, data options, formatting options etc. These properties can be applied at the entire application level or can also be individually applied at any component level as well.
You can read about those properties here.

D. Adhoc Report Designer (HReport) Enhancements
1. Custom Formatting Support
Advanced custom formatting support now allows users to define personalized formatting logic for numbers, dates, colors, accounting views, financial reports, and conditional styling.
- Negative values in brackets
- Green positive values
- Custom financial formatting
- Conditional numeric styling

2. Rename & Order By in Field Context Menu
Users can now rename fields and apply order-by functionality directly from the field context menu. Simply clicking on the dragged fields gives you these options. Earlier in order to rename you can double click on the field and rename. For sorting, there was sorting icon in the dragged fields. Those options are also present as well and can be used.

3. Tooltip Customization Support
So far, the fields which are part of the rows/columns/marks were only visible in tooltip with no option to control it.
From version 6.2.1, a new “Tooltip” property has been introduced which can allow you to add new fields which can be displayed while the report is being shown. Further whatever fields are being displayed in tooltip can also be controlled, removed, edited as well.

4. Stepped Color Options in Existing Color Property
From version 6.2.1, in the color property, a stepped color option is also added. In case if we are using gradient color, the stepped color option allows to specify the number of color steps between the minimum value color and maximum value color.

5. Percentage Values in Tooltip for Radial Charts
Tooltip support has been enhanced to display percentage values when radial property is enabled.
6. Text Visualization Renamed to Word Cloud
The existing “Text” visualization has been renamed to “Word Cloud” for better usability and clarity and avoid any confusion.
7. Configurable Drillthrough Default Option
Drill through property allows to click somewhere and open a detailed view in the same frame. There were 2 options present i.e. Drill Through & Drill Through Default.
- Drill Through: Opened child report based on where we have clicked thus showing limited data
- Drill Through Default: This opened the child report with all data (default values selected while configuring drill through)
In certain cases, to certain users, these 2 options could cause confusion. Hence, from version 6.2 onwards, there is an option to disable Drill Through Default. Hence it will only show Drill Through option only.
