SAP R/3 are ERP software using large database. Usually commercial databases such Oracle, DB2, Informix is used as its database server. Mine using Oracle

SAP tcode DB02 is use to check database size, tablespaces size, current statistic, checking freespace statistic, analyze detailed tablespace, checking missing indexes, and space critical objects. Actually, we can do more than that.

SAP R/3 installation created 6 tablespaces by default. Here are name of their tablespaces :

  • PSAP[SID]620

I am using SAP R/3 Enterprises 4.7 ext 200 version. It may be different if you are using old or new ones.

SAP R/3 data is saved on PSAP[SID] tablespace. So, we need to managed this tablespace carefully.

When you type DB02,

Press Space Statistic button to find out tablespace size and its growth. Tablespace’s growth can be seen daily, weekly, or monthly.

To check tablespace current size, just click Current Size button.

Click on PSAP[SID] tablespace and then, click Freespace Analysis.

If your PSAP[SID] tablespace size is reaching 95% level, you should consider increasing its size. You can use BRTOOLS to increase tablespace size. We’ll talk about BRTOOLS later.

    Hi there! I know this is kinda off topic but I’d figured I’d
    ask. Would you be interested in exchanging links or maybe guest writing a blog post or vice-versa?

    My website goes over a lot of the same topics as yours and I think we could greatly benefit from each other.
    If you might be interested feel free to send me an e-mail.
    I look forward to hearing from you! Great blog by the way!
