Dear experts,
I'm working on archiving data on NW 7.40 with HANA 2sp5.
Is there a way to find how much data is freed from disk/memory after object is archived?
The statistics in SARA for specific object seem to show much mor data deleted, than it shows in db size history in DB02.
What do each column in statistics mean?
On the screenshot you can see CO_ITEM object stats after archiving:

and below the actual sizes of tables in the object:

As you can see, the biggest table is 7,5GB now after archiving (test system)
On productive system now (archiving not done yet) it looks like that:

System copy was done before, so we have ca 12GB of data deleted from db.
Why do statistics show that we lost over 200GB if the tables were only 26GB big? How to get the real stats without checking table sizes before and after archiving? we have a lot of objects to archive with many variants each, so it would be hard to check each table from object, note down, and compare afterwards the space we gained.
It looks simmilar for other objects too.
Best regards,
Jedrzej
