The Number Format field allows you to specify a valid number format from those defined in Prospero.
Select the ellipsis button in the Number Format field to return a select list Number Formats defined in Prospero. After making the format selection, select the OK button to assign that format to the Line Definition row.
The Number Format you specify will force the line's data to be formatted differently from data defined in the Report Definition for the report.
Note: If the Formatting Fields checkbox is not checked on the context ribbon, this field will not appear in the Line Definition workspace.
