Merging 2 suppliers where POs are available for both the suppliers

Hi,

We have created two vendors in the system for a single supplier with a slight change in the name. POs were created with both vendors and we need to merge same and detactivate the incorrect vendor. My Quenstions are as follows:

1. Once the vendors are merged will the incorrect vendor will get automatically deactivared?

2.  Will the open POs with the incorrrect supplier will get merged with the correct supplier and will not face any problem in receiving the items under the correct supplier name?

3.  Receipts against the incorrect vendor will not have any issues when matching the invoices agaist the correct evndor once the merge is completed?
