How to add a company report
1. Open the upload form
Click Upload PDF Report, then start typing the company name. Listed companies appear with their stock code and market; you can also type a company that is not listed.
2. Choose the year and the PDF
Pick the Reporting Year, then drop the report PDF into the box or click to select it. Each company can have only one entry per year; a duplicate is rejected.
3. Submit and wait
Click Submit for AI Extraction and keep the window open — large PDFs can take a minute or two. When it shows Submission Successful, click Close. The new entry is at the top of the list with the status Completed.
4. Check the extracted numbers
Click the entry to open it. Each scope card shows the value, the report page, a confidence level and the quoted text it came from, and the header shows the PCAF DQS. If a number looks wrong, check it against the Source PDF.
