To Synchronize the Internal and Central Catalogs
Internal Catalog items must be re-linked to the Central Catalog whenever you open a design with a dependent catalog. It may be necessary to synchronize the Internal Catalog with the Central Catalog. When a synchronization error occurs, the Catalog Synchronization Required dialog box opens. When the Internal Catalog is not synchronized with the Central Catalog, it becomes independent.
