If you have determined that some of the Vouchers are not showing up on your 1099 Vendor Report and know which ones are missing, follow these steps:
  • Go to the History supertab in Accounts Payable.
  • Find the first missing Voucher in the History Tab in Accounts Payable and double-click to open it or click on the Item tab. 
  • In the middle of the screen is a field labeled 1099 Invoice . 
  • Check this box. 
  • Click Save.
  • Click on the Line Items tab and determine if the box assignment is accurate
  • Repeat for all missing Vouchers.
  • Rerun your report.
The 1099 check used to determine whether a Voucher should be included on the 1099 report is available for edit regardless of whether the Voucher is posted or not.  Thus, during the review process prior to printing 1099's, it is easy to remove or add Vouchers by checking or un-checking the 1099 box.           

If the 1099 box is checked, then the line items can have their boxes modified.  If the box is not checked, then the line item boxes are not available for modification.  Only line items with valid box numbers will show up on the report.
