How to assign unit of measure for quantity in ALV classes?

Hi guys,

I made a quick search and I did not found how to assign a column of quantities with respective column of units of measure (and amount columns with currency columns) in the class based ALV reporting approach. I am using classes cl_salv_functions_list, cl_salv_columns_table, cl_salv_display_settings, cl_salv_table, etc. Do you know where is this functionality? Thanks in advance
