manufacturing - I´m not able to receive a product with lot when the quantity has decimals - exemplo 2.8 - it gives an error message saying "qty must be a number"
this kind of decimals problem also happens when adjusting quantities (increase or decrease)
Yes, sorry I see that now that I look properly at the code.
Can you comment out (add // to the start of the line) all 4 lines of that section:
if(isset($_POST['Qty' . $i]) AND trim($_POST['Qty' . $i]) != '' AND !is_numeric($_POST['Qty' . $i])) {
$InputError = true;
prnMsg(_('The quantity entered is not numeric - a number is expected'),'error');
}
