Refreshing R/3 4.7 system from ECC 6.0 system

[bglobee]

HI Experts,

We recently upgraded the system from R/3 4.7 (BASIS release 620) to ECC 6.0 (BASIS release 701). For one of the test system, a cross version refresh was performed. (Sandbox system was in 4.7 and production system is ECC 6.0).

When the refresh was completed, we were not able to login in 000 client using any of the user ids including the standard ones. Seems like all the user ids were deleted in 000 client. Then we changed the sap* login parameter and restarted the system to reset the SAP* login. Later the user master was imported from production system to test system's 000 client.

Are there any special steps to be carried out to prevent the above said incident?

What are the special steps that needs to be taken care of in the scenario of 'cross version' refresh.

Please let me know your inputs on this.

Thank you.

When performing a refresh, your customer master data will not be deleted automatically.. Check on db level in table USR02 .

What do you mean exactly with cross-version refresh? You want to refresh an ECC 6.0 system to 4.7??

Kind regards,

Hi,

We refreshed a 4.7 system from ECC 6.0 production system in turn which automatically updated the 4.7 system to ECC 6.

Okay, so you have overwritten your 4.7 system completely with ECC 6.0. Have you also replaced the SAP kernel?

Hi,

I think you should explain how did you "refresh" the 4.7 system so we could find what could lead to the problem you faced.

What OS and DB do you have?

Hi Mark,

Yes the SAP Kernel was replaced.

OS - HP UX B.11.31

DB - ORACLE 10.2.0.4

There were no issues during the start of DB, appl after refresh. We imported the User master in the productive client that was backed up before refresh and imported the same after refresh. coincidentall, after the import of user master in productive client, this particular issue occurred in client 000. could this be a reason for deletion of user master tables in 000 client?

Are you importing the user master of 4.7 into ECC 6.0? If that's the case, it will not work..

Hi,

We imported the User master in the productive client that was backed up before refresh and imported the same after refresh.

This is why I'm asking you to tell us how did you "refresh" the system. Did you do a system copy?

Looks like you are trying to import User Master data generated in 4.7 into ecc 6 but that won´t work.
