Hi everyone,</div>
<div>I created a list of items with checkbox in each row to select the elements and update the date in the field att073.</div>
<div>My question is: it is possible select rows elegible to update, using the checkbox and reload the report in order to update that row?</div>
<div> </div>
<div>I tried use the javascript to colect the selected rows but I can't pass the js variable thought the dataset when reload the report.</div>
<div> </div>
<div>You have another way to do this? or idea?</div>
<div> </div>
<div>Thank you,</div>
