Chapter 11. Developing for Multiuser Dep... > User Accounts and Session Data
User Accounts and Session Data
One common use of global behavior in a multiuser environment is to set a global field with your currently logged-in account. This enables you always to have a central stored value that’s easy to use in calculation formulas and scripts. One could argue that simply using the Get (AccountName) function wherever necessary would accomplish the same end, but there’s an additional use for storing the current account name in a global: You can drive a relationship with it into a User table by using the account name as a unique match field.
Note
Note that a global variable, as opposed to a global field, cannot drive a relationship. This difference can play a significant role in determining whether to store particular session data in a global field or a global variable.
