What code is used for a follow-up on the shipment of a Non-RFI Transaction?

The correct code for a follow-up on the shipment of a Non-RFI (Request for Information) Transaction is BK1. This code is specifically designated to facilitate the process of querying the status of shipments that are not related to RFI transactions. Using BK1 allows personnel to efficiently track and confirm the status of these shipments, ensuring that they can manage logistics and supply chain needs effectively.

Each code has a unique purpose, and understanding these distinctions is crucial in maintaining accurate records and communications regarding shipments. The other codes available do not pertain specifically to non-RFI transaction follow-ups, thus solidifying BK1 as the appropriate choice for this particular scenario.
