hello,

i encountered odoo warning while saving the request for quotation. "The operation cannot be completed, probably due to the following: - deletion: you may be trying to delete a record while other records still reference it - creation/update: a mandatory field is not correctly set [object with reference: product_id - product". Before i make rfq, i made changes in the product id from required to not required (settings>UI>Views>p.urchase.order.form).


Please guide me how to save the request for quotation.


Thanks.

Hello @AR,

You did changes in Purchase Form through  Setting->UI->Views-> purchase.order.form.  It is not Permanent.
 
In purchase.order.line " product_id" field is required from py (python) file.
if you want to make it required=false then you must have to override product_id field and remove required=True.

for example:

class PurchaseOrderLine(models.Model):

    _inherit = 'purchase.order.line'

   product_id = fields.Many2one('product.product', string='Product', domain=[('purchase_ok', '=', True)], change_default=True, required=False)
or 

   product_id = fields.Many2one('product.product', string='Product', domain=[('purchase_ok', '=', True)], change_default=True)


You can override product_id field in your custom module.

Please Refer Below link and see the example of Inheritance
