In reports, I guess the views, I deleted one of the files there.

I tried to Upgrade but I get an error.

I know I shouldn't messed with the files, did a copy of the file but erased it by mistake.

Error code:

Odoo-serverfout

RPC_ERROR

This is the error code when I try to Upgrade

Hi,

1- If you're on:

Odoo.sh: You can roll back to a previous build.

Local instance: You can restore the file from your local Git history if you're using version control:

2- Re-import the Original Report File

If you have a backup .xml file of the report (e.g., sale_report_templates.xml), you can:

* Copy it into your module's views directory.

* Add it back to your __manifest__.py:

'data': [

    'views/sale_report_templates.xml',

],

* Restart the server and upgrade your module:

3- If you remove the report from the UI, try to upgrade the sales module.

Hope it helps

Quite some assumptions need to happen here:

1. Assuming 'erased the wrong file' actually means a (.xml) file holding view or template definitions:
2. 1. Assuming it was a file you've created or modified yourself in the past:
      No, unless your files are tracked in a svn (usually a GitHub repository) or you have a backup of that file that can be put at the original position.
   2. Assuming it was a core file (actual Odoo source code) that has not been tempered with by any other means up to that point:
      Yes, you can find the core files in https://github.com/odoo/odoo (Odoo Community source code), https://github.com/odoo/enterprise (additional source code for Odoo Enterprise, in case applicable to your setup). The branches selection on the left and the history button within a file allows you to switch to a very specific version of that original core file.
3. Assuming 'erased the wrong file' doesn't actually mean a file (which seems to be more probable) but a view stored in your Odoo database:
4. 1. Assuming it was a view you've created or modified yourself:
      No, unless your database has been backed up any time between your last modification to that view and its deletion.
   2. Assuming it was a core view (actual Odoo source code representation of that report inside your Odoo database) that has not been tempered with by any other means up to that point:
      Yes, you should be able to simply run an upgrade on the module that holds the definition of that view. You can do so from the Apps menu as well as from the CLI/terminal. In your case it would be the module 'Sales' (technical name 'sale'), but, upgrading 'Sales Management' (technical name 'sale_management') will be fine as well. However, you need to be aware about the fact, that ANY and ALL changes that have been performed in other core views of that module will be reset to its original state as well!

Also, future onwards - for above and so many more reasons: 
You really should not touch any core view definitions inside the database or their actual files. You will render your database 'un-upgradeable' [in the sense of bringing it to a newer version of Odoo] (unless manually recreating all these changes post-upgrade is something that makes you happy). Also also, installing other modules or upgrading them can fail in this scenario as well, due to the fact that other modules may depend on something you have changed or deleted within that view. See for example the 'Report Inheritance' tutorial: https://www.odoo.com/documentation/18.0/developer/tutorials/pdf_reports.html#report-inheritance

These changes should always be done in a custom module (or Odoo Studio, in case of Odoo Enterprise and your up for an adventure of sorts while upgrading to a newer version).
