Can we still use our head office location for back-to-back trades (where we don't store the material)?

For back-to-back trades, transactions must be linked to the location where the material is physically stored.

If you are selling material that is physically stored at one of your sites, you must select that site for the transaction, not the head office. On the other hand, if you are carrying out a back-to-back trade and the material remains at the seller's site, you do not need to select a location manually. The UDB will automatically link the transaction to the site where the material is stored.
