I'm looking for info about the data retention in warehouse database. As far as info in the documentation about Monthly & Daily Volume is clear, that about Jobs info is dependly of amount of users. I would like to know when it will be 3 months , when 4 and so on. What is the key to recognize for how long the Jobs data will be retained for some particular customer.
I think there's some confusion here.
Provided you're using BP 5.1 or above, Job level information is held in the warehouse database (psreports) for at least 12 months.
It can be held for longer, depending on how long user specified to keep the job data for when BP was installed.
Refer to the Blueprint Installation Guide for more details.
