The option to show the tag column in the Transaction Lists through the vendor profile is unavailable, accounting. However, I've got a workaround that you can follow below.
You can pull up the Transaction List by Vendor in a Modern view to add the Tags column and check which tags are associated with each transaction. I'll show you how.
- Go to the Reports menu.
- Locate and open the Transaction List by Vendor.
- Click Columns, and select More Columns.
- Type in Tags in the search bar.
- Click the Transaction dropdown and put a checkmark on the Tags available.
