As of version 1.6.5, you can define specific per-product rules for how a product is processed at your controlled drug machines.
Previously, CDMs could only apply charges to the bill without performing any other actions to the medical record. We have added a CDM Setup page to the Pharmacy Setup, which will allow you to define how each machine should handle the bill.
If the CDM is set to follow the routing rule "Product Setup" then it will use the settings you have put on this page to determine how a product is handled.
