class LotExpiration(models.TransientModel):

report_file = fields.Binary(string='Report File', readonly=True)
report_filename = fields.Char(string='Filename', readonly=True),error cumming from this part i think, error is

Hi,


The error occurs because Odoo cannot find the exclude_sublocations field when parsing the XML view. This usually happens if the Python model defining the field is not loaded before the XML, or if module dependencies are missing in the manifest.


In Odoo, XML views are loaded in the order specified in the module’s __manifest__.py. If a view references a field from a model that hasn’t been loaded yet, it triggers a “Field does not exist” error. Similarly, if the module depends on models from other modules (like stock.location), those modules must be included in the depends list to ensure the related models exist before XML parsing.


To fix this, ensure all necessary modules are listed in depends (e.g., 'base' and 'stock') and that the Python model is loaded before the XML in the data section. After updating the manifest, upgrading the module will apply the correct loading order and prevent the field-not-found error.


Hope it helps
