Use this field to define a column sequence number. This number represents the order in which the data will be displayed in the report. This field is mandatory.
The sequence number must mirror the logical order used in the standard, or master report structures delivered with your solution (Financial views '10' (expenses) and '20' (revenue)). For example, the first column must be the type of structure, the second column the project budget, the third column is a free column and so on.
You can define a maximum of 40 columns to display, per view.
