The situation may arise where it is needed to use a business partner in a journal entry. The following article will go over how to do so.
To use a business partner in a journal entry, you'll need to:
1. Click in the "G/L Acct/BP Code" field
2. Hold the Ctrl key on your keyboard
3. Then click the grey circle in that field OR you can hit the Tab key on your keyboard.
This will bring up the List of Business Partners window from which you can choose the appropriate business partner (customers are A/R, vendors are A/P). If you are using a Mac, you'll hold the "Control" key to do this.
