Hi,
If you see the bapi properly there is a Table parameters
PARTNERADDRESSES like BAPIADDR1.
Hope You have to populate all street details by that structure.
Like
STR_SUPPL1 = Street 2
STR_SUPPL2 = Street 3 .
Try like this.
Link sales order with this vbpa - adrc table with ADRNR field.
For rest code search in google.
Hope this information helpful.
Thanks
Gourav.
