Global ClassificationsGlobal classifications are classifications that all users have access to. Even if a user is restricted to the records of a particular customer, that user can always see global classifications.
Use global classifications at the top of classification structures that all users should have access to. At lower levels of the hierarchy, a particular customer might require other classifications in the classification structure that are not relevant to any other customers. Create such classifications as customer-specific classifications.
Classifications can only become more restrictive at each subsequent level of the classification hierarchy, so a global classification cannot have a parent that is a customer-specific classification.
All of your customers have desktop computers, so you make the following classifications global:
IT
IT \ HARDWARE
IT \ HARDWARE \ DESKTOP COMPUTER
Changing a global classification to a customer specific restricts the use of that classification to only the customers that are associated with that classification. Changing a customer-specific classification to become global lets all customers use a classification that they might not have previously used.
