Dear aneesh,
You sholud use the domain for condition. we can set domain in two ways
1. python file.
2. xml file.
we can choose any one way to set the domain.
So you should use domain like this
in python file
'section_id': fields.many2one('crm.case.section', 'Sales Team', domain="[('section_id', '=', 2)]")
or
in xml file
<field name="section_id" domain="[('section_id', '=', 2)]"/>
Thanks & Regards

Hi friend:
You have to add the *domain* which defines your condition.So, you can do it by two ways:
Either in your *python* file.
Or in your  *xml* file.
Here is an example: where field_a is the field that you want on it the many_2_one depends.( any number based on a value entered in another field? )
*Python* :
'section_id': fields.many2one('crm.case.section', 'Sales Team', domain="[('section_id', '=', field_a)]")
or
*XML* :
<field name="section_id" domain="[('section_id', '=', field_a)]"/>
