There was data loss in existing requests upon moving the changes from DEV instance to QA.
1. Renamed some fields
2. Creaeted new validations and replaced some old validations with this newly created ones(to meet the requirement).
Note: Data loss is seen only in the fields that were renamed.
Please suggest if there is any solution to get back the data.
Attaching screenshots for reference.
Have you checked the database (KCRT_REQUEST_DETAILS table) for the request..?
If the data already selected in the request fields are not in the list of values in the new validation, they may disappear from the UI but should still be available on the DB..!
