Forum Post: Trying to use BOI to create PO, issue with Vendor Number

Greetings, I am trying to use the following:  retVAL = oPOOrder.nSetKeyValue("PurchaseOrderNo$", sPONumber)         retVAL = oPOOrder.nSetKey()         retVAL = oPOOrder.nSetValue("PurchaseOrderDate$", "20140529")         retVAL = oPOOrder.nSetValue("OrderType$", "S")         retVAL = oPOOrder.nSetValue("VendorNo$", "TRENTNY")         If retVAL = 0 Then             MsgBox("Set Vendor Failed - " & oPOOrder.sLastErrorMsg)         End If         retVAL = oPOOrder.nSetValue("TaxSchedule$", "NONTAX") The error is telling me that the vendor is not on file. However I am using a valid VendorNo in my application. The other fields return a 1 so it looks like I have everything else set up right, I am just missing something with the VendorNo itself. Any suggestions? Thanks
