Is there any way to add Account Name and Account Code in Transactions (specifically expenses) report?

Yes, we can generate this report, sm722885. I'll walk you through the steps.

1. Go to the Reports section.
2. Search for the Expenses by Vendor Summary report.
3. Click the TOTAL amount to see the details of the transactions.

The posting expense accounts and their account numbers are listed in the ACCOUNT column, as shown in the screenshot. You can even group the transactions into Vendor, Class, etc., for easy tracking. Also, please note that each line represents a line item of every transaction.

You can also check about customizing reports for your additional reference.

Thank you @JessT for your reply. Appreciate it.

But I am looking to create Transaction report which will only include expenses and have additional columns of Account Name and Account Code fields apart from all the columns which QBO already provides.

You're most welcome, @sm72288.

I can suggest another report to ensure you can see the expense transactions that include their respective Account Name and Number (or Code).

To do this, you can pull up and customize the Transaction List by Vendor report instead. This way, you'll be able to add the said columns to your report. Let me guide you how:

1. Go to the Reports menu.
2. Select the Transaction List by Vendor report from the Expenses and vendors section. 
3. Click the Customize button, and then tick Account and Account # from the Rows/Columns section.
4. Go to the Filter section, and then select the expense transactions you'll want to include, such as bills, credit card expense, checks, etc. from the Transaction Type drop-down.
5. Apply other filters you'll want and then click Run report when you're ready.
   
   

If you wish to save this report, you can click the Save Customization button at the top. This way, you can quickly access it for future use. For more tips, please review this article: Memorize reports in QuickBooks Online.

Thanks for the reply @ReyJohn_D . 

This report seems perfect for the requirement for me.

The only problem which is there is that I am not able to see "Account#". Please find attached the screenshots for your reference.

Can I create custom column with name "Account Code" from Account and Settings and then can later try to populate the value from query (ReportService object)?

Please suggest how can I include Account code for my reports?
