Can someone help me to identify the list of suppliers included in the category purchases? i just want a breakdown to see how the expense is calculated?

Hello there, laurencehen. 

We have reports that shows the List of Purchases by Supplier Detail. You can also customize this report according to your preference. 

Here's how to run the report: 

1. From the left-menu, select Reports. 
2. In the search field, type Purchases by Supplier Detail. 
3. On the report page, choose the Report period.
4. Then, click Run report. 

Let me know if you need anything else in pulling up reports. Have a good one!
