A schema is a definition of the customer master that you wish to use. The schema can have as many Schema Field attributes as you choose to create.
Schemas drive the associated subordinate datasets for validation and column definition.
Schemas belong to a Business Area. Schemas that are defined within the DEFAULT business area are visible to ALL users.
Access to the ability to Create, Edit, View or Delete a schema is based on the permissions assigned within a given Role to a User. Under the least privilege model, a user that does not have access to the Schema Permission with appropriate User Rights cannot even view a Schema.
If a schema resides in a particular Business Area, the user needs to be assigned to that business area in order to access any objects within that business area.
You can access Schemas, if you have the permissions in your role, from the Ribbon navigation.
Define a new schema by giving it a name and a description. These attributes are used in the event logs to describe any changes that might happen to the schema over time.
You can start to add Schema Fields to the schema through the all-in-one screen. Further details on the field attributes are shown in the right panel.
After defining your schema you might next want to consider how you want to add master data.
