Can i know to to run report for a product to know over all transitions done on a product?

I can provide some clarification about the report you need in QuickBooks Online, Manish3.

Let's run the Product/Service List report so you can view the summary of the selling prices and purchase costs of all your products. I'll guide you how. 

1. Go to Reports from the left menu. 
2. Locate the Sales and customers section. 
3. Select Product/Service List to open the report.

If you want to combine to a single report, you can utilize Excel which helps give you the flexibility in combining these reports. You'll want to check this article for more details : Export your reports to Excel from QuickBooks Online.

Also, I've attached some articles you can use to help you customise reports, as well as personalizing transactions you enter in QuickBooks:
