You have a purchase order which you try to send to Ariba. The PO using the "discount in a kind" function so that an extry line item appears in the PO as bonus free extra beside the main item. But sending is ends in error:

"Error:quantity attribute at OrderRequest.ItemOut.ItemDetail.PriceBasisQuantity must be greater than 0 Please contact support with the Error Reference Number: ANERR-140000000000000001787741829 for more details"

Upon checking the to-be-sent cXML we can see the root cause:
<PriceBasisQuantity quantity="0.0" conversionFactor="1">
Due to 0 quantity in the PO it failed at Ariba Network as Ariba Network do not allow 0 quantity in PO
