Sometimes grouping list data by one or several field values significantly improves list usability. For example, you can group the list of Services documents by customer. This operation is available both in Designer and in 1C:Enterprise mode (on the More menu, click Configure list).
We recommend that you design list grouping as follows: if a grouping benefits all users, add it in Designer. List groupings added by users are only available to users who added them. Note that the same principle is applied to report customization.
