Question/Topic: How to rename data field name?
If you need some other data fields than those included in the program you can use the Custom Fields (almost all database solutions have several custom fields).
You can also change the usage of the predefined data fields. Just click with the left mouse button on a data field name that you want to redefine and select Rename ... from the displayed menu. Remember, that you can only change the field names and not the field types (e.g. a date field must always remain a date field).
