Hey Kristne,
There are several ways to restrict the DB grow,
First please follow according to:
SAP Note 706478 Preventing Basis tables from increasing considerably
The next step is to find the most largest table and growing,
you can do this in transaction DB02:
'DB Analysis' - 'Top n largest tables' and ' Top n modified
Now, you would be able to see which tables are growing,
if this table contains application data, than the growing must be
due to the growing in the ECC, and that's normal, otherwise,
you would have to check this specific table (and how you should reorganize this table)
p.s
you can also find the lastest tables by executing the following SQL:
select [reserved (MB)], [unused (MB)], [Table Rows],
right(space(16)left(user_name(o.uid),16),16)'.' as [Schema], left(object_name(i.id), 32) as [Table]
from (
select top 50
left(convert(char(18),convert(money,(sum(reserved)/128)),1),15) as [reserved (MB)],
left(convert(char(18),convert(money,((sum(reserved)-sum(used))/128)),1),15) as [unused (MB)],
left(convert(char(18),convert(money,(max(convert(int,convert(char(11),rows))))),1),15) as [Table Rows],
id
from sysindexes where indid in (0,1,255)
group by id
order by [reserved (MB)] desc, [Table Rows] desc) as i
inner join sysobjects o
on i.id = o.id
order by [reserved (MB)] desc, [Table Rows] desc
