Deleting Vendor locations in APO

While I thought it would have easy to delete vendors (1011 loc type) having done location deletion couple of times before, I am unbale to make use of any reports (PPORDER DELETE, SD ORDER DEL, RLCDEL, OM DEL) to delete any of the ATP orders that are shown to exist in WUF for the vendor locations in question. I also need to delete external procurement relations and t/lanes for some vendors that are no longer needed in the system.

These are the document categories I am trying to delete before I delete the vendors permanently from the system.

-Shipping notifications

-Purchase Orders

-Purchase requisitions

-Vendor confirmations.

Note that no products exist for the vendor locations (V_MATLOC)

Please advise.
