What can a purchaser do if they want to cancel part of an order?

When a purchaser wants to cancel part of an order, writing "cancelled" on the copies is a correct course of action. This method provides clear documentation of the cancellation and maintains the integrity of the order records. By marking the order copies appropriately, the purchaser indicates which items are being canceled and ensures that all parties involved—both the purchaser and supplier—are aware of the change.

Documenting cancellations in this manner is also important for compliance with regulations as it maintains accountability and traceability within the purchasing process. This practice reflects a responsible approach to managing orders and helps avoid misunderstandings between the purchaser and supplier regarding what is being kept or returned.

In contrast, notifying the DEA about the cancellation is unnecessary in this case, as the DEA only needs to be informed in specific situations involving controlled substances. Cancelling only after the supplier's notification complicates the process and limits the purchaser's ability to manage their order proactively. Returning all items and ordering new ones could be impractical and inefficient, especially when only part of the order needs to be canceled.
