If you want to run the script for all files in the directory structure, just use find:

find /var/data/2017/01 -type f -exec sh /opt/myscript.sh {} \;

Or with the Processing... lines (with GNU find):

find /var/data/2017/01 -type f -printf "Processing %p\n" -exec sh /opt/myscript.sh {} \;

If you only want to run on some subdirectories in the tree, you'll need to use -path or -name and -prune to limit the matches.

dir_proc=/var/data/2017/01
# maybe {1..31} because month can have 31 days
for day in {1..30}; do
    # check directory exist || otherwise continue with next day
    [[ -e $dir_proc/$day ]] || continue
    for file in "$dir_proc/$day/"*; do
        # check file exist      || otherwise continue with next file
        [[ -e $file ]] || continue
        # do something with "$file"
    done
done

EDIT with months:

dir_proc=/var/data/2017
for month in {01..12}; do
    for day in {01..31}; do
        # check directory exist || otherwise continue with next day
        [[ -e $dir_proc/$month/$day ]] || continue
        for file in "$dir_proc/$month/$day/"*; do
            # check file exist      || otherwise continue with next file
            [[ -e $file ]] || continue
            # do something with "$file"
        done
    done
done

Or shorter, with one for

dir_proc=/var/data/2017
for month_day in {01..12}/{01..31}; do
    # check directory exist || otherwise continue with next day
    [[ -e $dir_proc/${month_day} ]] || continue
    for file in "$dir_proc/${month_day}/"*; do
        # check file exist      || otherwise continue with next file
        [[ -e $file ]] || continue
        # do something with "$file"
    done
done
