Specific to cin7 Core

when a retailer sends a PO containing the C310 allowance code at the line level, the discount will be treated differently than usual by cin7. rather than populating in the additional charges section, the allowance will be applied in the "discount" column of each individual line item to which it is applied in the xml. 

in addition, when a C310 line item allowance is used for Cin7 Core, the 850 xml must have an AllowChrgPercent element included - if the percentage is not present, the client will experience upload issues when the invoice has been completed (generally will see the error "Export Error Error analysing record(s).A invoice line level allowance\charge was found before any invoice line. Please check the order of the lines on the invoice.").

this may be undesirable to clients. as a workaround, work with SPS to hardcode a switch to another allowance code, for example C300 "Additional Discount", which will not experience this same behavior.
