I recently added a custom Char field called 'Report No' to the invoice lines in Odoo 15,
using the following code:
class AccountMoveLineInherited(models.Model):
_inherit = 'account.move.line'
report_no = fields.Char('Report No', required=True)
However, when I enter a new invoice line record and save it, the custom field often gets lost.
I'm not sure why this is happening and would appreciate any suggestions or solutions. Thank you.

After encountering an issue where my custom Char field 'report_no' was getting lost when I saved new invoice line records in Odoo 15, I spent two hours troubleshooting the issue. Eventually, I discovered that the issue arose because the 'account.move' model contains two fields with the same relation to 'account.move.line', causing a conflict with my custom field. so I added the 'report_no' field in both one2many relation fields in the views

Hi,
Try with the field attribute “ store”.
Eg:
class AccountMoveLineInherited(models.Model):
_inherit = 'account.move.line'
report_no = fields.Char('Report No', required=True, store= True)
If this is not works, try with the force_save = 1 in XML
<field name=”report_no” force_save=”1”/>
Regards
