What do I load in the Code field?

In v10 the Code field is automatically populated with a TW number or numeric value. In v11 the Code field is mandatory and must be unique. What should I enter here when adding new users?

It doesn't matter what you enter here, but it must be unique and not interfere with any interface definitions of a provider code. The recommendation is to load your organizations mnemonic paired with a number, i.e. "GHC0001" (Galen Healthcare 0001).
