In order to display an ALV report with specific columns already sorted by default you will need to build a
sort catalogue. This is fairly straight forward and is done in the following way:
Step 1. Add data declaration for sort catalogue
Step 2. Add code to build sort catalogue table
Step 3. Update 'gd_tree->set_table_for_first_display' method call to include parameter 'it_sort'
* ALV data declarations data: it_sortcat type LVC_T_SORT, it_sortcatdb type LVC_T_SORT.
