plug-in reversible or not

Hi There

During the upgrade of plug-in for the PI_BASIS and PI in our 4.7 SAP system with HPUX and Oracle, I was able to update the plug-in PI_BASIS to 2005_1_620, however when I tried to update PI to 2004_1_470 I got the message

"OCS component does not match the current software component vector"

Then after redaing through teh Notes I found PI_BASIS 2005_1_620 can only be used with PI 2003_1_470 or higher but currently we are on PI 2002_1_470.

I guess plug-ins are not reversible so I am thinking a restore from backup will be the only option, after which I can start from scratch. Can anyone comment on this, as to if there is any other option.

    Patches are not'll need to restore from backup to return the previous PI_BASIS patch level.

    Now, why don't you upgrade your PI to 2003_1_470 or higher and avoid the restore?

    anything that goes into SAP via SPAM/SAINT (and you confirm the entry) is not reversible.

    there have been instances where SAP would login into your system and revert back changes only in cases where your SPAM / SAINT had terminated with errors and had left the system unusable.

    The bottomline is that , if you are putting something via SPAM/SAINT, make sure you have a complete database backup done before starting the patching.
