For an Administration Services Console session, you can specify which alias table is used as the active alias table (the table that is used when aliases are displayed or updated).
Independent of the Administration Services Console setting, you can set an active alias table for Outline Editor.
To set active alias tables for Administration Services Console sessions:
From Enterprise View or a custom view, select a database.
Right-click, and select Set, and then Active alias table.
In the Set Active Alias Table dialog box, from the list of available alias tables, select an alias table.
Click OK.
