When i choose any report and click any amount to see transaction nothing

It's my pleasure to help you with your first post in the Community, @yasowryh-gmail-c.

When you click the amount in a report, it should show the item details. I suspect that the reason for this unexpected behavior is browser-related. 

QuickBooks Online uses cache to help the page load faster. However, it could run into problems when it gets loaded with temporary internet files. 

To confirm, let's log in to your QuickBooks company using an incognito or a private browser. Follow these keyboard shortcut keys below according to your preferred browser: 

• Google Chrome, press CTRL+ Shift+N
• Mozilla Firefox: press CTRL+Shift+P
• Internet Explorer: Press CTRL+Shift+P
• Safari: press Command+Shift+N

Go back to your report and see if the item will show after clicking the amount, then start troubleshooting your main browser by clearing its cache. If it's still not showing you the details, try using another supported and updated browser.
