Every invoice requires at least one detail record that the rate codes will be billed under. You can have as many detail records as you like, but when you first create an invoice you are required to identify the first detail record to bill under.
When you are in Edit mode on an invoice, you will add detail records using the Add Detail button. Fill out the data fields for each item. All fields (except Cont WR#) are required to be filled in prior to saving.

Enter a ref# for your purposes. Any entry up to 12 characters is allowed
Enter the Vendor Ref# and Description for this detail record
Click Save when done. If any required fields are missing you will see an error screen as shown below. Correct your missing entries and click Save again.
