After I add the HST on on each line, and click save, when I read audit history, all lines are under one supplier. I tried to delete all transaction but not working

Hi there, 

Creating transactions for multiple suppliers is an important component of organizing your bookkeeping transactions. It's essential that you're assigning the proper expenses to each supplier in order to stay organized. I'd be happy to point you in the right direction for help. 

It sounds like you're creating a single expense for one of your suppliers. Each time you add a line item in an expense, you'll need to specify a tax code, which you've done. Note that each line item within your expense will be assigned to the supplier you've selected at the top of the page. 

It's essential that you're able to delete the transactions that haven't been entered correctly. The steps for fixing this issue may depend on how you've entered your transactions.

In this case, it might be best to reach out to our tech support team so an agent can take a closer look at how you've set things up. If you're not sure how to navigate the account to reach your goals, our agents have the ability to remotely share your screen and walk you through it. 

I hope this helps. 

Have a great weekend.
