I am using Transaction Detail by account Report and i cant find narration for payment column for both customers and vendors please help.

I can help you add columns to reports, kkkkkkkkkkk.

By default, the Memo/Description or Total amount column is displayed. If you're unable to see this column, you can use these steps: 

1. Go to the Reports menu and select the Transaction Detail by Account report.
2. At the upper-right, click Customise.
3. From the Rows/Columns section, select Change columns.
4. Select Amount or Memo/Description.
5. Click Run report.

If you're referring to something else, any additional information of what you meant by narration is much appreciated. You can use this article for more details about customising reports.

Keep me posted if you have other questions. Thanks and take care always!
