Pending vendor invoices can be submitted to the Workflow without any error message, even if there are missing mandatory financial dimensions. This is not the case with the Purchase order. When there is a missing mandatory financial dimension on the purchase order, an error message appears, and submit action is blocked (message attached). What is causing the inconvenience is that if the Pending vendor invoice is submitted to the WF without needed financial dimension values when the workflow is completed vendor invoice can not be posted. To post it, the user must turn it back to the first step in the WF, fill in missing data, and submit it again. These additional steps slow down the business process and lead to wasting time. In the end, latency can cause losing the right to deduct VAT.
