This error is a validation alert. It indicates that Unimarket has detected missing mandatory information or a data mismatch that prevents the invoice from being created or saved.

When this message appears, scroll through the invoice screen and look for red text, red borders around fields, or red exclamation icons.

Check the Header Information

The most common errors occur in the top section of the invoice form:

• Supplier Invoice Number: This field is mandatory. Ensure it does not contain prohibited special characters (avoid using # or &).
• Invoice Date: This must be a valid date. If the date falls in a closed fiscal period or is too far in the future, the form may block submission.
• Remittance Address: Ensure a "Remit To" address is selected. If the dropdown is empty, refer to help article Editing a Supplier Profile.
• Tax/Shipping/Discount: If you have entered a total in the header but the individual line items do not add up to that total. The form will remain in an "Error" state.

Check the Line Items

If the header is clean, the error is likely buried in the individual lines:

• Quantity/Price Mismatch: If you attempt to invoice for a quantity or price that exceeds the remaining balance (beyond your community's allowed tolerance), the field will turn red.
  • Note: Users cannot invoice a quantity of 0. If an invoice reflects a 0 quantity, ignore that line on the invoice and only invoice those with actual quantities included.
• Invoiced to Zero: Ensure you haven't accidentally set a line item to a quantity of 0 while leaving a price value present.

Check Accounting (FOAPAL)

In many communities, the accounting strings are validated in real-time:

• Missing Account Codes: Ensure every line item has a full FOAPAL/GL string.
• Inactive Codes: If a Fund or Org has been terminated in your ERP (Banner/Colleague) since the PO was created, the invoice form will flag the code as invalid.
• Permissions: Verify that the user submitting the invoice has the authority to post to the specific Chart of Accounts used on the lines.

"Hidden" Configuration Blocks

Sometimes the form looks perfect, but a background setting is blocking the "Submit" button:

• Mandatory Attachments: Your community may require a digital copy of the invoice to be uploaded. Look for a red asterisk * next to the Attachments section.
• Buyer Group Access: If the user's Buyer Group was removed from the supplier profile after the PO was created, they will be blocked from submitting the invoice.
• Supplier Status: If the supplier has moved from "Active" to "Disconnected" while the invoice was being drafted, the submission will fail.

Pro-Tip: If you cannot find any red errors on the page, try refreshing the page (which will clear the form) and create the invoice again.
