The interactions older than 6 months should be archived/moved to GENMCA database and purged after 7 uyears from archived DB.
If we run the following SQL statement on GENMCR we can see the interactions from 2011
SELECT * from interaction where startdate <TO_DATE(‘30/APR/2015’,‘dd/mon/yyyy’) order by startdate;
! Old interactions count in GENMCR is : 5,655,621
SELECT count(*) from interaction where startdate <TO_DATE(‘30/APR/2015’,‘dd/mon/yyyy’);
When you say they are finished you say because you business rules or because DB property. I talk, as Kubig says, about a flag on the DB. If your callflow has no control points then they won’t be considered as closed.
