Thank you for the solutions on how to exclude custom modules from the LoC count. I followed the suggestions, and I can confirm that the LoC for my custom modules are no longer being counted, which is a great step forward!.

However, the main issue persists. My Odoo Enterprise subscription has not been fully activated. The system still shows that I am on a trial or limited subscription, and I only have a month of validity.

I have already opened a support ticket with Odoo about this, but I have not received a response yet.

Given your expertise, do you have any suggestions on how to properly activate or link a custom Enterprise subscription to an on-premise installation? Are there specific steps I might be missing, or a configuration parameter that needs to be checked?

Any advice you could offer would be a huge help.

Thank you again for your time and assistance.

You need to indicate in the manifest of your modules that they are excluded from the CLOC count:

"cloc_exclude": [
    "lib/common.py", # exclude a single file
    "data/*.xml",    # exclude all XML files in a specific folder
    "example/**/*",  # exclude all files in a folder hierarchy recursively
    "**/*.scss",     # exclude all scss file from the module
]
