Custom Reports - Web Guide Links Broken

Hello,

I would like to build a P&L Report which shows divisions’ P&L inside a specific project. I think I would be able to build this with a custom report.

However, the website guides on custom reports are met with a 404 error (see below). I cannot see how to properly build a custom report. Is there a good source for this info?

@lubos (Sorry to tag, but I do pay for server edtion) Is there any correct way to learn how to make Custom Reports. Since the website guides are broken, AI isn’t doing a good job leading me through it.
