- 5002 error!!!

Question

hey All,
Does anyone know why this code would throw the - 5002 error with just a dash for the error description? it works for an update of an existing purchase order but throws the error when I am creating a new PO. Any ideas?
if (update)
    thisDoc.GetByKey(Int32.Parse(currentPO));
    thisDoc.Lines.Add();
   thisDoc.Lines.ItemCode = currentItemCode;
    thisDoc.Lines.ItemDescription = myItem.ItemName;
     //TODO ADD IN SALES ORDER AND PO NUMBER LINKS salesOrderNum
     //Set values to the fields
     thisDoc.CardCode = currentVendor;
     //Invoice Lines - Set values to the second line
               //poDoc.Lines.UserFields.Fields.Item("U_ShipFrom").Value = shipFrom;
     thisDoc.Lines.Quantity = Double.Parse(qty);
     thisDoc.Lines.Price = Double.Parse(cost);
     thisDoc.Lines.BaseEntry = Int32.Parse(salesOrderNum);
     thisDoc.Lines.BaseLine = soLineNum;
     thisDoc.Lines.BaseType = 17; // 17 is sales order;
               //poDoc.Lines.UserFields.Fields.Item("U_PQR").Value = pqr;
               //poDoc.Lines.UserFields.Fields.Item("U_LogNotes").Value = logNotes;
     int returnVal;
     if (update)
     //Update the purchase order
          returnVal = thisDoc.Update();
     else
          returnVal = thisDoc.Add();

Hi Curtis
I'm not sure if you can base a PO on a sales order, didn't realize you were doing that earlier. If you go to Purchase Order, you can't base it on sales order. The only way you can do it through the front end is if you tick the Purchase order box on Sales order form.....the system then creates one for you.
I tried on my own code that works perfect with invoice based on sales order. But as soon as i say PO based on Sales Order it gives the same error code. The description says something like the BP Codes are different. Now for this it must be different because it's not a customer anymore but a vendor/supplier. But all other circumstances the bpcodes would be the same for docs that are based on previous docs. I'm not sure if we can do it based. You might have to just create the PO without basing it on the sales order.
Hope this helps
