@rafat; looks like a bug:-
Looking at:-
File: \sales\inquiry\customer_allocation_inquiry.php
151: _("Due Date") => array('type'=>'date', 'fun'=>'due_date'),
and comparing with:-
File: \purchasing\inquiry\supplier_allocation_inquiry.php
142: _("Due Date") => array('fun'=>'due_date'),
The supplier due date is not given the type 'date': or any other type.
So in \includes\ui\db_pager_view.inc
its assigned as a normal labelcell:-
File: \includes\ui\db_pager_view.inc
144: else
145: label_cell($cell);
instead of a date labelcell:-
File:\includes\ui\db_pager_view.inc
114: case 'date':
115: label_cell(sql2date($cell), "align='center' nowrap"); break;
