The Brand's Master Catalog must exist on the live server before you can synchronize the Brand.
A Master Catalog cannot be synchronized by the Data Sync Tool, therefore you must either:
- Use the Import-Export Tool to export the Master Catalog from the authoring system and import it into the live system.
- Use the Commerce Manager to manually create the Master Catalog on the live system.
- Use database tools to extract the Master Catalog data from the the authoring database and insert into the live database. This should only be performed by a database administrator.
