We have instances where an EDI invoice from a vendor will contain materials that were ordered both via EDI and directly through the vendor. The EDI invoice in Polaris only includes the EDI ordered materials and then we add a line item for the materials that were not ordered via EDI.
In LEAP we are able to add a line item to an EDI invoice but we are not able to receive it manually like we are in the client. I have included a screenshot to illustrate this.
