Hello All,

I found solution for this, its two step process.

1) We need to push the latest dictionary of res.company model in module list.

     module.PosModel.prototype.models.push({

     model: 'res.company',

     fields: [ 'currency_id', 'email', 'website', 'company_registry', 'vat', 'name', 'phone', 'partner_id' , 'country_id', 'fax'],

     ids: function(self){ return [self.user.company_id[0]] },

     loaded: function(self,companies){ self.company = companies[0]; },

     });

Update the new fields in this fields list : fields: [ 'currency_id', 'email', 'website', 'company_registry', 'vat', 'name', 'phone', 'partner_id' , 'country_id', 'fax'],  I have added fax no , In base fax no is not used.

2) Extend the PosModel :

     module.PosModel = module.PosModel.extend({    

      models: [{

      model: 'res.company',

      fields: [ 'currency_id', 'email', 'website', 'company_registry', 'vat', 'name', 'phone', 'partner_id' , 'country_id', 'fax'],

      ids: function(self){ return [self.user.company_id[0]] },

      loaded: function(self,companies){ self.company = companies[0]; },

      },]

      });

This is how I achieved , Now I can access that field in Qweb part of POS. is there any better way to do this?

Thanks.

Anil.
