Is it possible to change the baseentry/baseline/basetype in document lines?

Question

Hi,
I have created a PO and a SO with same item in document lines separately. I want to set the BaseEntry, BaseLine and BaseType of PO lines to points to a item line in SO. My code is like below:
                po.Lines.SetCurrentLine(0);
                po.Lines.BaseEntry = xxxxx;
                po.Lines.BaseLine = 0;
                po.Lines.BaseType = 17; // Sales Order
When I called po.Update(), i got error code -5002 with error message : Item no. is missing  [POR1.ItemCode][line: 1]. I am sure when i called po.Lines.SetCurrentLine(0), it points to correct line. My question is Can I update the BaseEntry/BaseLine/Base in a existing document line item?
BTW, since the PO is created separately the BaseEntry and BaseLine are all empty or -1. Now, I am using DI 2007A.
Please suggest!
Thanks,
Lan

Hi Gordon,
I tried it again to create a new PO with all base document info in the line item, but this time I got error message: "Base document card and target document card do not match." with code -5002. The SO and the new PO have same line item and same qty. But I don't know what does that error message mean? Is it about business partner code? But they are different, in SO it is customer and in PO it is vendor. What's possible reasone for this error message?
Thanks!
