Hi Davide,

I hope, something like below code should help you. Please check.

var chk = 'true';

var gr2_task = '';

var gr = new GlideRecord('u_history_task');

gr.query();

while(gr.next()) {

var gr_task = gr.task;

if(gr_task == gr2_task)

chk = 'false';

else

chk = 'true';

if(chk == 'true')

{

var gr2 = new GlideRecord('u_history_task');

gr2.addQuery('task', gr.task);

gr2.orderByDesc('u_date');

gr2.query();

var count = gr.getRowCount();

var last = 'x';

gr2_task = gr2.task;

while(gr2.next())

{

current.u_order = count;

if(count == gr.getRowCount())

current.u_last = last;

current.update();

count = count - 1;

}

}

}
