Create a connection for each source database that you want to archive data from. The source database is the database that stores the transactional data that you want to archive. It is usually the production database or application database. For restore jobs, it is the history database, where the data was originally archived to.
To restore archived data, create a source connection for the target or history database. In the restore scenario, the target database now becomes the archive source.
To retire a SAP application, create a source connection for the database in which the SAP application is installed. You must enter the SAP host, client, and other SAP details in order to create the connection. If you do not correctly enter the SAP host, the File Archive loader cannot map the SAP datatypes to the Data Vault datatypes.
