Corridor - Invoice Rejection: LINE ITEM UNIT COST cannot be zero.
The problem is in the IE line item. Given that only one invoice level credit line is allowed per invoice, since the IF line and IE line are both credits, they should be combined and entered as follows:
20141007|30057318|1001|100011|3844.52|20140901|20140930|Services|7002764|IF|1.00|-51473.98|-5147.98|20140930|||||Fees -1,356.38; Expenses -3971.60 Credits Applied|44-064999|0.00|||2012-0001
No Task Codes or Expense Codes are required for invoice level line items.
