  how to remove sum of total in group by
  In OpenERP 7 List view time data added using the below code:-
  'in_time' : fields.float('In Time'),
  <field name="intake_time" widget="float_time"/>
  In List view selected "Group by " any fields Header shows Total In time Value
  How to remove Total In time value ? [in xml file not added sum keyword but group by still shows sum time ]
  Hi,
  Probably a bit late!
  You could override the read_group method like this on you model:
  def read_group(self, cr, uid, domain, fields, groupby, offset=0, limit=None, context=None, orderby=False):
  if 'intake_time' in fields:
  fields.remove('intake_time')
  return super(MyClassName, self).read_group(cr, uid, domain, fields, groupby, offset, limit=limit, context=context, orderby=orderby)
  I let a 'c' on the if condition, unfortunately, I haven't enough karma to edit my own post!...
  I completely agree with this method, I tried it and it works! Thank you.
  Thanks for this tip. It still work in Odoo 8.0
  By the way I fixed the extra 'c'
  Not too late at all. Thanks. Still works on Odoo 9.0.
  Ok after struggling with another issue on the pivot view, I figured out this hack is causing problem... seems like the pivot view is confused on the groups and javascript is crashing when selecting measures or "Expand all". I think the js code can be fixed to fully support the hack here and I will fill a ticket at Odoo.
  There is no issue with the pivot finally!!! Problem is that last line should be:
  return super(ReportDetailInvoice, self).read_group(cr, uid, domain, fields, groupby, offset, limit, context, orderby, lazy).
  The default Float field value for group_operator shows sum of value
  Reference link
  Currently "Group by" Field values able to change to min, max, avg
  But unable to remove group by value
  i applied group_operator = None or group_operator = False but its still shows sum of total. How to group_by remove sum or set to value None
  Any update?..
  Hello Prakash,
  By default OpenERP Will consider 'SUM' as group operator . So you wan't be able to remove this behavior easily by any sort of configuration or xml code. For this you need to make changes in the orm.py in
  def read_group method and comment out the code that adds the default 'SUM' to integer and float fields at line 2664.!
