Changing PO vendor in ME22N.
As per some of older threads it is not possible to change a vendor once the PO has been created.
But in our case we can change the vendor via me22n.
click in the vendor field.F4.alternate payee.Enter a new vendor.
The vendor changes.
I want to know if this is a standard SAP practice.Also the address and other data changes.
Please provide any insight on this issue.
