we are Creating STO with ME27 tcode from one plant to another plant ie from A120 to S122.
Already the configurations are done by someone.
Now i took the purchase order xxxxx and open in me23n.
As per the process we need to Assign  vendor to Delivering plant
ie XK03 >Purchasing view>Extras>Add. Purchasing data>Plant
I have the supplying plant and want to find the vendor to which it was
assigned. I searched the ME23n Tcode and not found the vendor(envirnoment-vendor).
