Changed Delivery Address is not coming in PO Print Preview

Hi Gurus

The scenario is, While creating a PO I am making changes in the Delivery Address at Item Level.

And when try to print preview before saving the PO, the changes made are not coming in the preview. while after saving the PO, those changes are reflecting in the preview.

So Is there any way by which I can fetch those changes and can see them in the print preview of PO before saving the PO???

fields are : NAME1, NAME2, NAME3, STR_SUPPL1, STR_SUPPL2, NAME_CO etc.

I am fetching these fields on the basis of ADRNR from Table T001W.

Any kind of help will be appriciated.

Thanks in Advance.
