thank you for your reply, as your direct i can't find the group Technical Features (base.group_no_one) .

would you please tell me how to do to show partner_id in crm.lead

Thanks

Hi,

If you are saying that the field is visible only in debug mode and not seen in the normal mode, the field might have assigned the group Technical Features (base.group_no_one) , once this group is assigned for a field it will be shown only in the debug mode.

See: How To Show Field Only In Developer Mode

Thanks
