Group Loop Start
Group loop start, each iteration processes another
group of rows. The column(s) to group on need to be specified.
The input data table is sorted based on the specified columns before
looping starts, by default. Sorting can be switched off if input
data table is already properly sorted based on the columns to group
on. If sorting is switched off, but input table is not properly
sorted execution will be canceled.

If checked, the input data table will not be sorted before looping
starts. The table must already be sorted properly by the columns to
group on. If sorting is switched off, but input table is not properly
sorted execution will be canceled.
