Calculated attribute change log cannot be viewed
In the settings of the attribute there is a «Track changes» flag, after applying which any changes in the attribute will be recorded. This flag can be set only for non-calculated attributes. History cannot be saved for calculated attributes, since calculated attributes are subject of computation and their value is always unstable.
All changes to the attribute values are saved in the system change log. To view the change log, open a record, click on the «Information» button on the ribbon of the form and select «Change log».
Solution
If you still need to store change log of calculated attributes, then:
- Create a non-calculated attribute (for each calculated one).
- Manually (or by scenario) write the calculated value in the new attribute.
