There are typically four steps of archving:
Preprocessing
Write
Store
Delete
Normally Store is invisible to users as it is automatic with write. Also Delete can be configure in a way that it automatically triggered after Store.
What to mention is that only Write has the variant related to application.
The Store and Delete is only decided the data for processing via the archving session/key. There is typically no variants in Store or Delete job.
When the job is scheduled (manually or auto triggered), it will create entry in table ADMI_JOBS. In this table, the job name, job count and the session/key is maintained.
Later when the job starts, it looks up for this entry to know which session/key to proceed.
