A group of fields is a few columns for which data is generated together. A group allows the user to work with similar fields changing generation parameters only in one place. A group consists of the first defining field and fields that depend on it.

A group is processed depending on the fill method applied to the defining field:

1. For methods "Random", "Ignore", "By mask", "List" and "Value Library", exactly the same methods and generation parameters that are applied to the defining field are applied to dependent fields.
2. For methods "By SQL statement" and "List from disk file", not only the first column in the file or the result set, but also columns following it will be used. Values in these columns will be used to generate dependent fields.
3. Such a group operation cannot be applied for methods "Incremental", "From Table" and "Expression".

To create a group, select the necessary fields and click the +G button. To delete a group, click -G button when the cursor is on the first field of the group.
