The Schema Privileges drop-down can contain a number of items with check boxes next to them. Each of these represent the name of a deployment, followed by the name of a component schema in that deployment. By checking the box for each item, you grant that user the ability to cost using the VPEs associated with that schema, and to view the component schema within the deployment.

This means that users can be restricted so that they can cost using the VPEs associated with a deployment, without being able to view all the component data.

Consider the example shown in the preceding image:

This user has been granted access to all data except the component data in the Aerospace – Military schema.

The Default Schema drop-down specifies what the user will access when first logging into aPriori. This contains a list of all the items that were selected for that user in the Schema Privileges drop-down. The system administrator can select what data users will see when they first log into aPriori.

A user may change what schema they are connected to at any time, by clicking File->Switch component schema… from the aPriori client toolbar and selecting from a list of all the schemas to which the user has access.
