Change request fields are not showing up in data picker. Some of the change form related fields are not showing up.
Fields like start_date, end_date are not present.
Please note the 'Parent' field is a reference to 'task' table, not 'change_request'. The columns mentioned Planned start date (start_date)/Planned end date (end date) are columns on the change_request table. This can be seen at the following link. Please expand the change_request table on the schema:
From this we can see these columns do not exist on the task table, but rather the child table change_request. In this case, from change_task you will need to dot walk through the 'Change request' field which references change_request table.
